Codebook & Documentation

Reference guide for all columns, grades, sizing values, odds bands, and section descriptions used in this report.

Metric Columns

ColumnDescription
BetsNumber of settled bets in the bucket (result ≠ blank)
W / L / PWins, Losses, Pushes
Win%Wins ÷ (Wins + Losses) — pushes excluded from denominator
AvgOddsMean American odds across all bets in the bucket
BE%Break-even win rate implied by AvgOdds: 100/(100+odds) for + odds; |odds|/(|odds|+100) for − odds
Net UnitsSum of profit_loss_units across all bets; positive = profitable
ROI%Net Units ÷ Total Units Risked × 100. Sized bets use actual sizing (FULL=1.0, HALF=0.5, QRTR=0.25); unsized bets treated as 1.0 unit risked.
*Caution flag: bucket has fewer bets than the --min-sample threshold. Results may be noise.

Grade Scale

GradeMeaningRecommendation (v2_rec)
AHigh conviction — strong edge, good line valueBEST_PLAY
BModerate edge — worth adding to a ticketGOOD_ADD
CMarginal / conditional edgePASS
DWeak edge — not recommendedPASS
FNegative edge — lean againstHARD_FADE

Note: C and D both map to PASS in v2_rec, so Grade is strictly more informative than v2_rec for performance analysis.

Sizing Values

SizingUnits RiskedIncluded in "Sized Only"?
FULL1.00Yes
HALF0.50Yes
QRTR0.25Yes
(blank)1.00 (implicit)No — unsized

Props are always unsized and will not appear in sections A–G when --sized-only is active. Section H always shows full prop data regardless of the --sized-only flag.
