RPM Gauge marking O-360-A1A FP

[maus92]

I had to delete my RPM gauge from my G3X system, and re-enable. Lost the RPM arcs / marks in the process. I'm wondering what others are using. I was using 2700 redline, green arc up to 2450, yellow arc between 2450 and 2700. Not sure if this is optimum...

For a certified Sensenich metal FP there is a yellow arc below 2350. IIRC 2150 to 2350. No reason for the upper yellow arc. The parallel valve engines really like 3300 r/m for acro.
