True HP reward formula: time/0.6 + 20*hour
- Full formula: time/60*100 + 20*hour (time is in minutes)
=> In simpler words, what percentage of 60 is the current time.

Real results might differ due to Tank taking some time to be killed
=> Survivors might get a tiny bit more than what is calculated in the formula
