Update after opening 1000 The Show packs this year.
16 diamonds pulled resulting in a 1.6% success rate. Getting 16 or fewer successful tries occurs about 1 in 5 times. Uncommon, but not a rare occurrence.
At this time I have opened 189 Ballin packs. I have pulled a diamond 12 times for a 6.3% success rate. This rate is at the 48th percentile. A typical result.
Where I think I am completely unlucky is the value of the diamonds being pulled. The current total value of all my live series diamonds pulled is 383,468 stubs (sell now price) for an average of 17,430.36 stubs per diamond pulled. I have only pulled 6 of the top 25 most expensive based on the sell now price with Bobby Witt Jr. being the most expensive card pulled with a value of 150,223 stubs. I have pulled 16 of the bottom 23 Live diamonds. If all the diamond cards have the same odds of being pulled this outcome is EXTREMELY unlikely. It is in the range of a ~3.4 sigma event. This is the kind of outcome that would be considered statistically very rare. It points to the fact that SDS is misleading pack buyers of the odds of getting the higher value diamond cards. If not all diamonds are pulled at the same rate, then pack buyers should be made aware of the odds to pull each individual card as the odds of pulling a diamond would be misleading to the pack buyer.
