Reward example calculation:

Prize pool	Total questions	Winners
250 SAO	10	5

Formula:

Rate

rate = round(4-(round(answerTimeSec / (questionTimeSec / 4))))

Reward

reward = (prizePool / ((totalWinners * totalQuestions) + totalPts + totalRate)) * (totalQuestions + pts + rate)

Winner #	PTS	Rate	Points	Reward
#1	0		10	~21.74
#2	10		20	~43.48
#3	20		30	~65.22
#4	30		40	~86.96
#5	5		15	~32.61
