Fascinating! Thanks for posting that.
So, If I'm understanding the chart right a 28" runner will peak at ~5100 RPM with the 2nd harmonic at a strength of 10%. A 14" runner will peak at ~3600 RPM with the 3d harmonic at a strength of 7%. A 7" runner with the 4th harmonic will peak at ~2750 RPM at a strength of 4%.
% of what?
