[Elecraft] K3 Keyer speed?

[John Oppenheimer]

Using an oscilloscope to measure dot leading edge to dot leading edge,
therefore ignoring weight. K3 in TX mode. There is some timing jitter,
used average observed values. Using the formula DOTms = 1200 / WPM

K3 WPM	ms	DOT ms	WPM
15	156	78	15.4
18	127	63.5	18.9
20	116	58	20.7
25	91.2	45.6	26.3
30	75.2	37.6	31.9
