I've been ripping these things all day, about 4 sets.. I'm up 3.1 mil (9.6-12.7) and after my 3rd Henry I decided to keep one.
I feel like there's 2 different algorithms on these packs. I figured this out because when I get to like 50ish packs the game freezes and I have to reset the game and when I get back into the store I can see the difference in pulls. I've also found out I can get it to give me either algorithm 1or2 and also prevent the freezing by just quitting mut at the menu and re-entering.
1) Lots of 89s and 93s but 0 96s, also the 3rd round will almost always be golds.
2) Lots of 84s but you DO have a chance at a 96..So far 1 96 each run, and the 3rd round gives mostly golds but also mid elites to 92's.
I have no data to support this, but I do prefer algorithm 1 as it allows me to get my training much quicker.
Also there's something with those variety packs. Once I hit 4-5 silvers in a row I said wtf so I switched to the other one under (training) and it hits purple strats and platinum again. Now switch back in fourth (any silver/greens more than once = switch) I swear this works try it.
