K3 Keyer speed versus display read out of speed

[Phil Hystad-3]

Does anyone know the accuracy of the K3 keyer speed and the display readout of the speed.   I am thinking that the speed of the keyer is faster then the display readout says that it is.  I am guessing close to 20 percent faster but I have not done any real measurements, just comparisons of other recorded CW where the speed was specified.  Of course, it is possible that the recorded CW that I used was also wrong but I am thinking the K3 is faster then the display readout says that it is.  For example, when the display readout shows 17 wpm, I am thinking this is about 20 wpm.

I've found that mine is usually reading fast by 1 wpm than I'm sending.  I've also found this to be the case with 2 other units that I've tried.  This has been tested with CW reading programs on the computer.

So who's right?  A lot of this stuff in the one unit range has to do
whether the number is rounded up or down, or simply has it's
fractional parts truncated.  When one has a very busy CPU running all
kinds of features in parallel in software, I'd vote for truncation and
all sorts of speed ups that tolerate minor non-consequential
inaccuracy.  Want processing budget available for more features.
Yaayy.  Something that corrects a minor inaccuracy and also runs in
same or less processing budget, then fine, but there is a prioritized
list for firmware changes, and a limited processing resource.
Consequential stuff first.

73, Guy.
