I have already stated I know exactly why how the current PDE ended up as is. So don't go there.

I can tell you 0 studs failed on the previous design (that was a $30 part). They were not brass.

Nothing scientific, just subjective impression based off the teams I work with here in Texas, and the lack of outcry on CD. If it was a very common problem, you'd see a lot more about it here. Look at the kerfuffle on the BAG Motors. By Paul Copioli's count, it's something that's affecting a very small percentage of motors, but there's several teams on here talking about it.

Here is a data point: We have six of these boards on various robots. We have one a broken stud. Relatively untrained student screwed on a 1/4-20 nut with an experienced mentor looking over her shoulder. Definitely operator error in our case.

We are now powering that PD board through a Wago connector for a test bed.
