all very interesting.(no sarcasm)
unfortunately in any calculation there will be missing facts of the kind that businesses will not publish for various reasons.
for example they might have a "hidden" factor that increases chance after having spent an x amount of cash so as to have a balance between "we will take as much money as we can from you" and the player's toleration upon accepting failures untill getting the desired result versus the part of ragequitting and never spending a dime on the game anymore.
this leaves us with incomplete calculations because it lacks certain values/factors.
especially when programmed, an RNG's randomness can be manipulated in many ways.
so in conclusion it still seems to me the best way to approach this is to get what you can, enhance chances by shopping and/or farming, and, mainly: dont worry about it.
Thats the thing behind my post. If you really want to check if the true underlying percentage is 10 % then you can do it with enough data + checking p values in hypothesis testing and arguing about possible errors like measurement error or omitted variable bias, which should be the case in this situation.
