Cost per spin at GQH and bonus stage in janan version are 20 stamia and 10 stamina like here.

Many high level player at japanees servers have have more then 600 (10 hours) in max stamina so they dont wast any stamina.

Well, every level you gain raises you max stamina by 3, plus another 3 if you fill the extra friend slot. That's 6 stamina per level, plus a base of 25 stamina in lvl1.
To have 430 stamina (needed for 10 spins in Stage 9), you need to be above level 68 (Lvl68 = 427sta, Lvl69 = 433sta), which will require a total exp of around 230k... Without factoring triple-exp spins, peronamins, or lvl-ups, for someone like me (Lvl46) that would take about 100 days to reach. And that's playing 24/7. Double that to take account of non-playing times, and then remoe around 10% for lvl-ups and exp-spins, and we get half a year for me to reach that.

Of course, this is one of the places where GHQ shows its fallacies: the 0.75% sta/exp rate turns that half year into 230 days.
However, just factoring in events, I believe we can cut that time down drastically. Right now, I'm sitting on 60 stamina refills from peronamins I collected in PeroColo. If we have one of those every 2 months, that means I might be able to remove up to 25% of that time in 4 or 5 months.
Of course, then, guards event sta/exp rate rears its ugly head in: 33%.

In the end, outside of paying players (some of which are already quite close to the 70s in their levels), I don't think we'll see much people reaching the 400sta line until Christmas this year.
