Try making the contiguous thirds beat the same within the first=
 A2 - A3 octave, then adjust the C# and F downwards for the 4/5=
 ratio.   Alan, I'd stick with the temperment you've been using=
 the most and not try something new for the test.   That's a=
 mistake...imho

I'm trying to settle on a temerament to take th RPT tuning test=
 with. The Sanderson makes a world of sense to me except for one=
 little thing ...
 
After setting the double A octave, it says to tune the C#s and Fs=
 to make contiguous 4:5 ratio thirds. Not problem except ...
 
How does one tune four notes at the same time???
 
I'm guessing you tune F3 ~7bps then wiggle C#3 around and see if=
 you can make that end work, moving F3 if it doesn't. Then you=
 would tune F4, wiggle in C#4 to make that end work, and see how=
 your C# octave came out ... ?  
 
Seems like a big leap the sequence to just say tune these here 4=
 notes. Am I close???
 
Anyone on the list actually use this for the test or as their=
 regular aural sequence?
