b) I also thought the zeta tuning involved doing (t+s)/2, where t and

s are two successive renormalized zeroes?

c) Is there any way, if you ever have a sec, I could get a list of the

first few zeta zeroes unrounded? I'd appreciate it and it would be

useful for me to figure out what the heck is going on.

That seems to be the zeta goodness figure which works the best.

That can also be done, and is a lot easier.

I'll email it. Do you want the actual zeros, or the zeros normalized so as to correspond to equal divisions?

But now you're saying we just take the location of the minimum or maximum?

Can you send the normalized ones for equal divisions, just unrounded?

I'd much appreciate it.

Computing a figure of merit and computing an octave retuning are two completely different problems. For the latter, there's another method which is lightening fast but which isn't as easy to justify, by the way.
