Tach time can vary from 15%-18% depending on engine rpm and some older style tachs registered time with just the electrical on. Al Hobbs and Tachs should have an oil pressure switch installed. You usually can reset the proper time on either if needed.
My plane only has a hobbs. Next time my mechanic woeks on it I'm going to see if we can verify how it's actually connected. Flew yesterday and it seems to be working OK. I'll keep an eye on it.
You do know since your airplane is experimental you could check to see how it is wired. If it was a SLSA after you get your sport pilot certificate you could still trace the wire circuit.
