March 27-29 | Ledger Recap

Welcome back to the ledger recap. I'm Alex Mercer, across from me, as always, is Marcus Webb.

Marcus, we just closed out a midweek weekend stretch and look, the record looks good, but

we've got some things to unpack. We always do.

Before we get into the film room, quick reminder for the desk on how we track. We work in

prediction market units. If we buy a contract at 60 cents, we're risking 0.60 units to

win 0.40, pure risk-based accounting. What we put in? What we got back? No fluff.

Alright, the tape. Session record, 14 wins, 3 losses, 1 push, 18 positions total. Net

on the session, plus 5 units.

Which sounds great until you do the math. Say it, 14 wins, 18 positions, and we netted

5 units. That's an average of roughly 35 cents of profit per winning contract. We were

buying a lot of 50 cent contracts to win 50 cents. That's fine, but when your win rate

is this high, you have to ask whether the position sizing matched the conviction.

We'll get into that. Overall, record now sits at 297 and 252, with 15 pushes, plus 10.1

units on the season. The ledger is green, but Marcus is right. The efficiency question

is real, and we're going to address it. Let's go to the film room. Let's start with

the one that still stinks. Clippers minus 8.5 against Indiana. We bought at 53 cents.

Final score, Clippers 114, Pacers 113.

One point. We needed nine. Walk me through it.

The thesis was sound on paper. Indiana was shorthanded. The Clippers had home court and

the line implied a comfortable double digit cushion. But here's the systemic issue. The

Clippers were a big at multiple points in that game, and Kawai Leonard, who is historically

a closer, took over late. The problem is that we needed a blowout, not a close win.

And Kawai closing games means the Pacers stayed competitive enough to keep it within striking

distance.

He hit a game-winning jumper at 0.4 seconds, completing a 24 point comeback.

Right. So here's the chain. Indiana was down big, which forced them into a pace in

space survival mode. More threes, more possessions. The Clippers, comfortable with the lead, went

conservative. Slowed the pace, protected the rim, stopped attacking. That let Indiana

claw back. And when Kawai sealed it at the buzzer, it was a one point win instead of a ten-point

win.

We needed the blowout. We got the thriller. Bad beat or bad thesis?

Honestly, bad beat with a structural flaw. We should have been more careful about buying

a large spread position on a team with Kawai Leonard, a player whose entire identity is

making close games closer, not blowing them open. He doesn't pour it on. He finishes.

That's a real market in efficiency. We priced wrong.

Noted for the playbook. Loss minus 0.53 units. Now let's talk about the Spurs, because

this was a two-position night and both hit. Spurs minus 17.5 at 55 cents, and Stefan Castle

over 16 and a half at 46 cents. Final scores, Spurs 127 bucks 195.

32 point margin. Castle went for 22, both settled green.

The bucks were missing Yannis. That was the thesis.

That was part of the thesis. Here's the full chain. Yannis is Milwaukee's entire defensive

anchor and their primary offensive initiator. Without him, the bucks have no credible interior

presence. They can't protect the paint and they can't generate half court offense at

a high level. The Spurs, meanwhile, are a young team that thrives in transition and open

court situations. When you remove Milwaukee's rim protection, San Antonio's guards and wings

get downhill all night. That's exactly what happened. And Castle, 22, 10 and 10 historic

triple double for a rookie, which brings me to the Alpha question. We were right. We were

also too safe. How much did we leave on the table?

The Spurs won by 32. We bought minus 17.5. They were almost certainly all spread contracts

available at minus 22 minus 25. If we had the conviction to buy the spread at all and

we clearly did, we should have been asking, what's the highest line we can justify given

what we know? A minus 25 contract against a Yannis list bucks team on a Spurs 8 game

winning streak. That's a position worth exploring.

So the missed Alpha is real. It's real. We made roughly a unit combined on these two.

A more aggressive spread position could have doubled that. The conviction was there.

The aggression wasn't.

Alright, let's talk about the one that made everyone look twice. Raptors minus 1.5 first

half at 56 cents. We bought it. Final halftime score Toronto 70 Orlando 43 27 point halftime

lead. The Raptors set an NBA play by play error record with a 31 O scoring run spanning

the first and second quarters. Scotty Barnes had 15 assists in the game.

Here's the systemic lead on this one Orlando's defense is built around their half court scheme

switching protecting the paint forcing mid range. But when you go down 20 early, you have

to abandon that scheme. You start fouling, you start gambling for steals, you extend

your defense and the Raptors who have been playing fast all season with Barnes as the

engine absolutely feasted on that. The 31 O run wasn't random. It was the Raptors punishing

a defense that had to overextend. And the first half contract was the right vehicle here.

But again, aggressive alpha review. We bought minus 1.5 at 56 cents. We won by 27 at the half.

If we had conviction on Toronto in the first half, why weren't we looking at minus eight minus

10 first half contracts? The implied probability on a blowout first half was underpriced given

what we knew about Orlando's recent defensive struggles. Mist alpha. Significant mist alpha.

The Sabers minus 1.5 puck line at 42 cents. Final Buffalo 3 Seattle 2.

Scuff won the game, lost the contract. They won by one. We needed to.

The thesis here was that Seattle was in a spiral. Bad road record, nothing to play for,

Sabers at home. And the Sabers did win. But here's the chain of causation on why they didn't cover.

Rasmus Dahlene scored his 100th career NHL goal in this game. That's a milestone moment.

Those games have a funny way of tightening up emotionally. The crowd goes electric,

the opponent digs in, and you end up with a gritty one goal game instead of the clinical win you

projected. And Shane Wright went down with an injury after a hit. Which actually helped Seattle

in a perverse way. When you lose a key player, the remaining guys tend to consolidate,

play tighter, and the game slows down. That's exactly what happened. Seattle lost their best

forward and responded by playing a suffocating low event third period. One goal game, we lose the

contract. Bad beat or bad thesis? Structural flaw on the puck line. A minus 1.5 contract in hockey is

a 42 cent position. You're paying for certainty that rarely exists in a sport decided by one or two

goals. We were right on the winner. We were wrong to demand a two goal cushion in what was always

going to be a competitive game. Let's end the film room on a clean one. Jared Allen over 10.5

points at 49 cents. Heat Cavaliers. Allen goes for 18 Cleveland wins 149 128. First game back from

a knee injury and we bought the over. That's the contrary and angle. Most of the market was probably

discounting him returned from injury, load management concerns rust. The implied probability was

essentially a coin flip at 49 cents. Right. And here's the systemic logic. Cleveland won by 21.

When a team wins by 21, their starters are playing meaningful minutes in the first three quarters,

accumulating stats organically. Allen didn't need to be good. He just needed to be present and

functional in a blowout that kept the starters on the floor. The market priced him like he might

struggle. We priced him like he just needed to play. Max Stross going off for 29 and 83 is against

his former team that actually helped us. Miami was so focused on stopping Stross that Allen had

clean looks all night. Exactly. Stress pulled the defensive attention. Allen operated freely in

the paint. Chain of causation. That's the thesis working as designed. All right, Marcus. Playbook

update. What did the session teach us? Two things. First, conviction calibration. We went 14 and

three this session and made five units. That's a structural problem disguised as a good result.

When we have high conviction and we clearly did given the win rate, we need to be buying more

aggressive contracts, alt spreads instead of the main line, tighter props, positions where the

market is further mispriced, not just slightly off. The spurs game is the case study. Perfect case

study. We knew the bucks were dead without Giannis. We knew the spurs were on a run. We bought

minus 17.5 when the game suggested minus 25 was the sharper position. The conviction was a nine.

The aggression was a six and the second lesson puck line discipline hockey minus 1.5 contracts

are traps for teams that win close games unless we have a strong structural reason to believe a

team will win by two or more dominant power play opponent on a back-to-back significant gold

ending gap. We should be buying the money line and accepting the lower payout. The saber's

game is a direct day of point right team wrong contract structure. So the rule update is in hockey

default to the money line unless the two goal case is explicit and documented. That's the rule.

Write it in. That's the session 14 and 3 plus 5 units. The ledger is green, the algorithm is

sharper and the missed alpha is now on the board which means next session we come in with the

calibration dialed up. Iron sharpens iron. Before we go remember everything we discuss here is a
