Pitybreaks in Genshin prior to the 90 guaranteed pulls normally reset the pity counter.
However, this simulator consistently gives a 5☆ at the 90th pull, regardless of whether a pitybreak occurred prior.
e.g. 5☆ appears at 20 pulls, the counter should reset and therefore give the next guaranteed next 5☆ at 110 and not 90.
I've experienced this on character banners since the Venti banner version of this simulator was released, haven't tried Weapons banner however.
Extra edit: This also seems to happen on a smaller scale
for 4☆s with single pulls - regardless of pitybreaks, one will appear every multiple of 10 (compared to when the 10 max pity should reset whenever a 4☆ appears)
