HT tuning checks

[Jerry Hunt]

I have borrowed Owen Jorgensen's "Tuning the Historical Temperaments by
Ear" from my local library and am keen to start trying some of the HT's.
In tuning Major 4th's and 5th's pure, are the M3-M6 and M10-M6 checks
valid for checking that the interval is pure. That is, testing that
M3=M6 or M10=M6.

Many thanks for your input.
