comment Variation of Coupon Collector's Problem
All of the parameters in the geometric distributions are halved, hence mean doubles... I do not understand your explanation, but you probably understood it. You can view as getting a geometric (p) but rejected with probability 1/2. This halves the parameter.

surely, this is just the answer of the normal problem, doubled?

Well, yeah, I agree with you. This is a bit stupid and misleading.

comment Profit Share Distribution > 100% Total?
I googled your first line of text. So, what they meant is that suppose, I make £100, you lose £20, then the total profit between us is £80, then I make 125% of the profit you make -25%. My profit ratio is my profit / my profit+your profit. Similarly for yours.
