Are these spikes occurring with Protrack turned off? I did see worse guiding with Protrack turned on. It stopped when I turned it off.
Protrack seems a bit hit and miss. Martin Pugh said to turn it off as it worsens yet with my CDK and PME it improves things. But on the PMX it seemed to worsen at my home observatory on a portable pier (perhaps not as rigid as my other 2 permanent piers).
Of course wind and seeing do come into it as does guide star selection. But a spike isn't guide star selection. It can happen in cloudy conditions when a cloud interrupts the guider for a few cycles but I assume you realise this. Same with wind causing spikes.
