As a PPL I have a headache from just reading all this.
It seems such an unnecessarily complicated set of procedures to follow in the very infrequent event that you will need to. It seems too complicated for a human brain to follow in a moment of heightened anxiety. Unnecessarily so. A computer could do it, but not a human. Too much room for error when it's not a task that is practiced repeatedly.
Bring back the cables and vacuum gauges, I say!
