Yeah, I would be too. One thing you might be able to do to "calibrate your
discomfort" would be to climb to an altitude where you cannot get more than 75%...
like 8000' or so. Verify your power at 75% cruise and lean to best power. Note the
mixture position. Linearly interpolate the mixture/altitude from that...

If it's your plane, I'd consider adding a cheapie CHT and EGT from Westach.
They're not that expense and it lets you have more real information on engine health.
Not really useful for cruise leaning, but good for a climb leaning and to verify
non-roasted engine CHTs.
