Every input is public. The base rate comes from the actual release record on the official changelog, then each signal nudges the odds and the full multiplier stack is shown on the tracker. The serious signals are the release record, the weekday pattern, and Yoshi's forum activity. The rest are jokes with real data behind them. "Major" means an update with big patch notes, measured, not guessed. Pizza demand is a typical curve for the hour, not a live reading, and is weighted accordingly.
