For this example, I will be using my account and puppet master’s theater.
In a dungeon, think back to how many people on average are in each dungeon you have done. For me, (I do puppets with about 4 people on average. Some more, some less.)
Think back and guesstimate how many times you have heard people call themselves getting white bags. (When I think back, I have heard probably around 30+ white bag calls.)
Here’s where you see if you’re lucky or not. You divide the number of white calls you have heard (+ any you have gotten) by the average number of people in each dungeon you do.
For puppets, I would divide 30 by 4. 30/4 = 7.5.
If you have gotten a lot more whites than the number you got, you are lucky. If you have gotten a lot less, you are unlucky. I have only gotten 1 puppet white I’m unlucky, but I knew that.
And remember to account for some error with your guesstimates: If I had gotten 5 puppet whites, I could be about average.
