The way I heard it, the m14 should beat similar to the M3 above the upper note (in the temperament area). In your example, above, the m14 would be about 5-1/2 beats, in theory. The beats slow down as you descend and I'd recommend a cross check with other tests. It's a good way to check for smoothness. Tom -- Thomas A. Cole, RPT Santa Cruz, CA mailto:tcole@cruzio.com
