Does anyone want to propose any guidelines for 7-limit temperament searches? What must be included, and what should not be?

Yes.

If you provide me with a wide-open list (using only your badness
cutoff) of maybe 40 or 50 temperaments, I'll try to find some points
where my gradual cutoffs agree with some sharp ones.

It would be easiest for me if your list was in a form easily imported
into Excel, i.e. everything relating to a single temperament being on
a single line, with no brackets.

I use brackets for matricies and wedgies--are you saying use parens instead? What should be on this single line?

No. I meant use nothing of that kind, although it's not a big deal if
you do. Doesn't matter much if you want to have commas too. The main
thing is to have one temperament per line.

At least:
Generators in 1:2
Generators in 1:3
Generators in 1:5
Generators in 1:7
Periods in 1:2
Periods in 1:3
Periods in 1:5
Periods in 1:7
RMS-optimum generator (cents)
RMS error (cents)

Thanks.
