Long answer:
When I first got the car I used the dip stick exclusively. I had no faith in the dash gauge. One of my friends was a long time Porsche owner and suggested that the dash gauge was actually quite good. I did some tests over a period of time comparing the dash gauge to the dip stick. Hmmmm, on level ground the dash gauge is right on. Ok then, on my car it does actually work as designed.
Short answer:
Dash gauge at start-up.
70+ track days, 100k miles and counting...
