I'm getting an average of 65 points per hell mode run, which is 25~26 stamina all the way to the end and 600 points every bonus run, which fills up by the same amount of stamina you use (1-stamina = 1% Bonus gauge).

So for running hell mode, that's 1200 points per 100-stamina, multiplied by 5.33 (magatamas x stamina cap) a day (out of 160 free at the 400k mark) plus that daily 400 stamina..........ew math.

If you have a stamina cap of 100, then 5.33-magas a day will net 11,200 points, then maybe an extra 1200~2400 if you levelup once or twice, up to 12,400~13,600 points a day. Ok, that's not enough. Even if you convert 20-Free magatamas into those paid magatamas, that would still come out to 13,600~14,800, 1800 points short of the daily requirement.

So unless someone can find a better method of farming points, you won't even break even out of going for the full 500k event points. It would however just BARELY break even if you stopped at the 400k mark, which means you'd get 160 magatamas of free stamina.
