Coming back after a night gives a different result than playing that night live

A game that skips time with a quick formula often disagrees with what the same hours would have produced tick by tick, usually in the favour of nobody. This entry shows how to make the skip use the very same rules as live play and still stay fast.

Why this works

Two ways of computing the same hours only agree if they follow the same rules. Rounding, limits and stalls are part of the rules, so a shortcut formula quietly plays a different game. Running the real rule step by step keeps the two worlds identical.

When not to use it

When time away is short or the growth never settles, stepping through every moment is too slow. Then cap the time you credit, or work in larger chunks, and accept a small, known difference instead of a freezing screen.
