# Research decisions from this conversation

This is a substantive handoff summary, not a complete verbatim conversation export. It excludes internal tool/runtime instructions and unrelated personal context.

The initial request was to evaluate every Portland game, consider matchups, home/away, rest, travel and injuries, sum win probabilities, estimate the final record, and update after games.

The first model used market totals as priors. Its October 10 expectation was 41.464 wins, central 80% range 32–50, P45+ 33.2965%, P50+ 12.4895%. The user explicitly rejected the market-anchored benchmark and requested an independent basketball model. That original state and code are retained and clearly labeled, not relabeled or rewritten.

The replacement model uses official NBA game logs for opponent-adjusted offense/defense, empirical year-to-year retention, roster/development assumptions, home court, relative rest/travel, altitude, modest matchup interactions and recovery timing. It sums 80 assigned-game probabilities and two unassigned NBA Cup-dependent slot mixtures. Preseason and the Cup championship do not count in the 82-game record.

The user emphasized Nori, Lillard, Morant and development by Henderson and Cissoko. The model credits player changes and development but assigns zero numerical benefit merely for a coach's one-year contract. Portland's central projection assumes 58 appearances for Lillard and 60 for Morant, with injuries, departures and small-guard fit deducted. Impact grades are analyst assumptions.

The independent October 10 expectation is 44.606014703773454 wins, median 45, central 80% range 32–57, P45+ 51.0185%, P50+ 31.3215%. Seed 202610102; 200,000 simulations. Shared team/availability uncertainty affects many games together. These broad tails are model outputs, not validated coverage guarantees.

Portland's exact projected season minutes sum to 19,680 (82 × 240). The other 29 teams use explicit team-level offense/defense adjustments rather than an estimated all-player impact model. Rotations and health projections inform their assessments and uncertainty.

The held-out 2025–26 historical foundation had Brier score about 0.2333 versus 0.2500 for constant 50% forecasts. This does not validate 2026–27 subjective roster changes or season-total tails. Proprietary shot-quality tracking, consistently garbage-time-filtered possessions and reliable future lineup impact were unavailable.

Two quality-control corrections before publication: neutral-site games were properly handled in held-out home-court validation, and Detroit's obsolete Duren holdout discount was removed after checking the extension announcement. No regular-season game has yet been processed. The known October 7 preseason result is Portland 123–118 Golden State (0012600033), not a new alert.

Robinhood context: screenshots showed Yes prices of 94/79/58/39/19 cents for 30+/35+/40+/45+/50+ wins, respectively. The 35+ order preview bought 123 contracts for $99.43, giving an 80.84% all-in break-even rate. The 45+ preview bought 243 contracts for $99.63, giving 41.00% break-even. These are historical user-supplied snapshots; no trade was submitted here. Those prices did not determine the independent model.

Future updates must verify/deduplicate official results, preserve actual pregame predictions, fit all-team regular-season margins once with an independent preseason prior equivalent to 20 games, refresh availability without double-counting, resolve Cup slots, simulate the remaining season and retain prospective Brier/log-loss history. The initial builder alone does not automate these steps.
