RE: Toolchange reliability
I guess. I don’t over torque them. My approach is to not over torque them and instead every few prints test each dock to ensure the bolts are secure. It’s not that big a deal. I also marked each spot on the grill that covers the area so I know where to slide the tool in.

The problem is, in the absence of proper torque figures, none of us has any idea if we are overtorquing them or not. What I do know is that significant force was required to seat my docks (way more than the included hex key could apply). I ended up having to use a T-handle style hex key. From reading up on here and other places, it seems support is advising that "significant" force is required to properly seat the dock bases. Some have quoted them as saying "a lot more than you may think you need."
Of course, your guess is as good as mine as to what "significant" means.

RE: Toolchange reliability
Blue threadlock is perfectly fine to use here.
If you use a threadlocker, then the torque spec can be different as the threadlocker initially would lubricate the threads and possibly, allow over torquing before reaching the torque limit.

You would think Prusa would have a value. Somewhere there has to be an industry standard for that screw size and thread pitch? Right?

Note: he posted an update in the comments of that video. He mentioned that if you properly lubricate the coupler pins ( https://help.prusa3d.com/guide/how-to-lubricate-the-coupler-pins-on-original-prusa-xl-multi-tool_636777) then you don't need to use the bump mod, i.e. the tool heads mount more consistently.
