Thanks for that. It is handy, but not entirely what I’m asking. From last season there seemed to be a huge swing in getting legendaries at all from gambling - something like 10% chance on gloves, but only 5% chance on boots. (I’m making that number up, but I think the extremes were something like that.)
So for instance with a Demon Hunter, I may have a 1/9 chance of getting the set gloves I want, but a 1/11 chance of getting the set boots. But if I can get 2x as many legendary boots as legendary gloves in the first place, I’m better off gambling boots instead of gloves.
But I’m trying to be really careful here not to confuse my anecdotal experience with actual statistics. Maybe it’s been bad luck that I’m getting 5% legendary gloves and 10% legendary boots; but maybe it’s designed that way.
What I’m talking about can be seen in posts like one bug report titled “Kadala Double Legendary Buff is broken”. See a copy of the findings below. What I’m curious about is whether it was the buff that was broken, or if the buff worked and the baseline results are uneven?
Different Gear Slots Have Very Different Kadala Success Rates
Conclusion: The Kadala Buff has been applied to some, but not all, gear slots.
Method
I tracked the following Kadala gambling. (In addition to my original post)
Boots
1054 “Kadala Trials”
92 Kadala drops
8.73% = Observed Success Rate
Gloves
692 “Kadala Trials”
130 Kadala drops
18.79% = Observed Success Rate
Chest Pieces
515 “Kadala Trials”
50 Kadala drops
9.71% = Observed Success Rate
95% Confidence Intervals
For each gear slot, lets estimate 95% Confidence Interval for its “Kadala Success Rate”.
Boots
8.73% = Observed Success Rate
0.87% = Standard Deviation
95% Confidence Interval for “Boot-specific Kadala Success Rate”
8.73% plus/minus 1.7%
7.03% to 10.43%
Gloves
18.79% = Observed Success Rate
1.48% = Standard Deviation
95% Confidence Interval for “Glove-specific Kadala Success Rate”
18.79% plus/minus 2.91%
15.883% to 21.7%
Chest Pieces
9.71% = Observed Success Rate
1.89% = Standard Deviation
95% Confidence Interval for “Chest-specific Kadala Success Rate”
9.71% plus/minus 3.71%
6.00% to 13.42%
Kadala is bugged … but its predictable and repeatable.
