Time penalty

Time penalty is how many points you lose in a run for spending time clearing floors, and it varies according to the events you've cleared throughout the run.

The formula(s) behind Time penalty are as follows:

TimePenalty = Floor(Ceil(((Rush_Bonus + Mega_Satan_Bonus + Lamb_Bonus + XXX_Bonus + Stage_Bonus) * 0.80) * (1.0 - SecondsPenalty)))

Where SecondsPenalty is:

SecondsPenalty = Exp((Elapsed_Seconds * -0.22) / BaseStagePenalty)

And, in turn BaseStagePenalty is the sum of several fixed amounts of points per each stage and event, called "Expected Stage Times":


 * from killing Satan / Isaac in stage 10

Using a Forget Me Now or a 5-pips Dice room will not alter those values.
