I'm saving for her too, got ~170 pulls right now
The average (50% chance) rolls required for C6 is I believe 662 exactly
Also need to factor in the R1
I think it's just under 40 Starglitter per 100 pulls, so 8 free pulls per 100
Fact is, there's no real purpose to worrying too much about any of the numbers much, because when the big moment comes, it's all left up to chance regardless. Just save save save every primopenny.
