David, I agree with you both. I've heard Al say 1-88 was best, but I do it your way for one simple reason; tuning the bass is easy for me, so I do it last. It seems to not mess up anything already done. Besides, I HATE to tune the upper two octaves last, when I'm getting tired. And, that way I know it's right on with the tenor, wherever it is. I've had many times when tuning 1-88 when the bass didn't quite agree with the tenor. then what do you do?? Change the tenor, or the bass? Many won't agree. Fine. Do what works for you. But after 31 years, 2 of which I experimented a lot, I'll tune the bass last. My 2 bits.

You can't start checking intervals and their relationship until you're nearly half way through your tuning. If you don't like some of the relationships at that point you either just leave it as is, or go back and correct and do over what you've already done. I start at F3 and go up through the temperament to A4 checking intervals and make sure it's as I want it before finishing out the piano. I also do unisons as I go to check unisons. I really do trust TuneLab like I trust my banker but I still count my change. dp David M.

He had conducted a study to see which tuning order produced the most stable tunings. The answer was to start at A0 and tune unisons as you go all the way to C8. That was one of the reasons I went to an ETD. Some are worried such a procedure will cause the plate to crack from uneven stress. Plates are so over-engineered I doubt it could make any difference.
