At the recent uber support meeting, we used dual buttons to check for a possible bug. We found a few spins where the predictions were a bit suspicious. I checked them carefully on the recorded video and found they weren't the result of bugs at all. The data is consistent with the ball simply traveling a different distance to what normally occurs, and the ball fall beeps and actual ball fall point being coincidental. When it happens live, it just seems odd to actually watch it happen. I'm not saying there is definitely no bug - just that what we thought may be bugs in the support meeting weren't bugs.
On another occasion with dual buttons, the ball travel time was incorrectly calculated as 0. As far as I recall this only ever happened once in my testing so it is very rare, although shouldn't happen at all. Another player experienced it a few times, so I'm still looking to reproduce this and have it fixed. But it is rare enough to not be a problem.
