Please note that this assumes that you have just had terrbile luck and not gotten one on the first 6 tiers, if you did get one lets say on tier 4 - then you would reset your counter. Right I gotcha sorry when I read your original post it suggested that the chance *per tier* was still increasing beyond 6. The line you wrote, i.e. "If you buy a 7th you have a 32.78% chance of having drawn an R5 "

It's not. You still have a 15% chance when you buy your 7th. It's just your chance of getting one if you buy tiers 1 through to 6 and 6 again (ie 7 times), are 32.78% chance I think is what you're saying.

And just because I'm trying to warn people off Mobage's ridiculous odds remember Grim's maths is only for your first half of the x10.
