Whoa, a $400 mistake from a missed loop bug is brutal. That line about it skipping the last entry is such a classic off by one thing, funny it took a different model to catch it.

Dielectric grease is thick stuff, so it will feel snappier longer just because it takes forever to move out of the way. That said, it is not really the same job as Krytox. Krytox is made to stay put and keep a smooth glide, while dielectric grease is made to keep water out, so it can get gummy over time and pick up dust. The reason yours feels better is probably that you cleaned the old lube off first, not the grease itself. Fresh lube on clean plastic beats old lube every time, no matter what brand it is.

Doubt PB Blaster did anything, you just finally broke it with all that cheater bar force.
