I've seen both sides of this: a PIP for a person who was falling behind that wasn't possible for the person to achieve because they were in a role without the skills needed to succeed in that role, and a PIP that was based on one supervisor's bad opinion of a particular person that was easy to accomplish when put in place by a different supervisor.
It all depends on your use case. It can get below zero F here (northern Minnesota) for weeks at a time, but I don't regularly drive more than 10 miles round trip.
As a second/town vehicle, a cheaper EV sounds great for conditions I can't use the e-assist cargo bike.
I have a stack of statistics books that I will flip through if I need explanation or illustration of a new concept. Usually one will help me out better than the others, but the combination of the different explanations usually improves my understanding.
I suppose this is really a parallelization of the "third textbook" model (i.e., if the third textbook you try when learning something new seems "much better" than the first two, it might because you actually did learn some things from the first two).
