Something really weird just happened regarding this. My emerald Penny normally has a 75 off dribble 3pt. The dynamic duo with Shaq raises it to an 80. I just put a +6 off dribble 3pt shoe on him, and it went up to a 91. What the hell?
I tried this again with acceleration. The duo raises it from 83 to 87. I put a +6 acceleration shoe on, and it is now a 97. Tried again with the purple UA +9 acceleration +3 SWB shoe, and accel is now a
99. SWB is a 99 as well!
If shoes simply stacked with the duo boosts, then accel SHOULD go from an 87 to a 96. But it went +12 to 99. SWB should have gone from a 93 (with the duo) to a 96.
This could be huge. What if the duo boosts are calculated in some odd way using a percentage, and stacking shoes and dynamic duos leads to super-boosts?
It's either that, or a glitch in the stat readings that doesn't work in-game. My next step is to check the box score in-game, and also see how Penny feels in-game (although that's less quantifiable).
Update: Checking the box scores gave me 0 information because they don't even show the dynamic duo boosts. Speed with ball is also missing from the in-game stat sheets. Wtf 2k?
Penny feels insanely fast though. This bug (because I think that's what this is) works with any stat that is already boosted by the duo, on any player. Also tested it on my roommate's XB1 account. I don't think it's too hard to believe that in a game riddled with glitches and oversights, one thing slipped through that actually benefits us.
