I recall that you mentioned that in your = tempered octaves tuning you are +75 cents by the time you get to C8. = Those tuning with normal stretch are more likely to reach only +40. For = your system that would require additional stretch going up. For others, = they would end up considerably sharp of the target and have to do a = lowering before a fine tuning.
