It's been slowed a bit because I've been having to stop to parse unclear/incorrect illustrations. And slowed a bit more because I'm bothering to stick post-its over them with corrections.

It's as though nobody actually checked if the instructions worked

They put tracking dots on his lower jaw, but not his upper jaw. If you watch footage of puppet scooter, you see the top mouth plate moving around like crazy. I bet the upper jaw flexes down more than they anticipated and not putting tracking dots on the upper jaw didn't give them that data.

Like in good puppeteering you are only "supposed" to move the lower jaw, but that isn't exactly how it works out in practice. I've seen footage of henson himself describing how muppet lipsync is sort of like throwing the words out of the character's mouth. The whole hand sort of goes forward, the thumb drops and the fingers move up.
