There is a 20% chance you will roll a 1 (1 in 5 chance = 20%) you don't roll a 1 so try again there is now a 40% chance you will roll a 1 (2 in 5 chance = 40%)
See, this is why I said you don't understand % as it applies to random chances. The first time you roll, your chance is 20%, or 1 in 5. The second time you roll, your chance is 20%, or 1 in 5. The third time you roll, your chance is 20%, or 1 in 5. It is not cumulative, and
it never changes! It's not 20%, then 40%, then 60%. It's 20%, then 20%, then 20%. Previous and subsequent rolls have no effect on the current roll. That is what you're not understanding. Yes, you are just being unlucky right now. And the people that are being lucky right now are understandably not complaining about it. It is possible, though not likely, to be eternally unlucky. It is equally possible, though just as unlikely, to be eternally lucky. There will be some players everywhere on the curve between lucky and unlucky. Bottom line is you were right that it is a 20% chance on your first 10 battles after you collect, but completely off base on that 20% being cumulative.
