Thanks for your reply, mate! And kudos for your activity in the forums lately. Glad to see that Bubbles BuzzerBeater's disposition towards BB is now again positive. ;)
@1) Coach Parrot is pretty accurate for the most part, so I too trust this to be close to the actual % but since I have virtually no experience with past-the-cap-training, I was hoping for an input from someone who has done it for a long time, intentionally. On an NT player probably...
@2) Yep, I've seen some players who are well past their perceived max potential as well. I agree that probably there's no such thing as "hard cap", except when the player reaches 34 ofc. Just hoping for a confirmation from Justin, but he is not so inclined to share "inside info" recently, rightfully so.

@3) As I said - that's just a speculation but I myself believe that there are some serious grounds to consider that those effects are actually present. Whether it's a bug or it's indeed intended to work that way I can't really say.
