Jeff – thanks. Agree it should be lower, but I think I’m significantly lower. The tach time appears to be about 60% of the Hobbs. I wouldve estimated 80-90% as you alluded…. I believe 2300 RPM will result in 1 hr of tach time equal to one hour on the closk/hobbs. On a recent cross country, I logged about 24 hours on Hobbs, with only 14 hours on the tach…
