Assumes 3 minutes per play to account for song length, loads and menuing. (Obviously this number will vary in practise)
Assumes event ends 2059hrs Tokyo time (UTC+0900) if End Date is used.
Multipliers are applied for the entire period of the event.
The simulation runs as if all your stamina is stored into a giant pool and you play all your games at once on the exact last minute of the event. Obviously not physically possible, but there's no intention to change this.
The algorithm spends ALL your stamina, even if you could stop earlier and reach your point target. This results in fringe cases where the Upper bound is slower than the lower bound because it has more stamina to spend.
If "Event Points" is selected as stopping condition, stamina is always refilled in batches of 100, even if less is needed to reach the goal.
