IMO pressure gauge is kind of an "oh ****!" gauge. If you've lost oil pressure, you're already screwed (e.g. in the instance of a cracked oil pick up). At least oil temp provides you with a usable reading that you'd constantly be referencing (e.g. when to beat and when not to beat on the vehicle). It's personal preference; do what you want.
P.S. I really like your car and I dig your style. Your method is thorough as well, I appreciate that.
