The new data is still truly weird.
When you did the GA, you had clear PE in RA and a flat ( but drifting ) line for DEC.
You then did the DEC lash test, and once more, the mount appears to go at 2x the commanded rate.
What is very interesting tho is how the distance moved for a common pulse seems to alternate ( massively )
on every second pulse???
( following is an extract from the debug log to show the extreme variability in reported moves for common pulses )

You then did a cal that appeared to work reasonably well ( and gave results that matched the beginning )
and in this case, the DEC appears to have moved almost as requested ( tho with odd spacings per pulse ).
Whats weird is the RA never came back the full distance ( possibly due to PE )
but the DEC returned to zero well before expected.
It then started guiding in DEC reasonably, but at a set point,
it got a larger error and then swapped into large oscillations.
The 2 interesting bits here are when it went into large oscillations, it also lost the underlying linearity of the DEC drift
almost as if some pulses have got lost????
Looking closely at the oscillations, you can also see that when they start, the pulses sent to fix them
appear to get ignored?? ( ie Kens theory they are being stacked up somewhere )
This stack up error is whaht we saw in the early IOptron firmwares.
