Thanks for your reply. Logs here: https://openphdguiding.org/logs/dl/PHD2_logs_BqZp.zip
I should probably have added that my imaging scale is 1.04"/px. So it's probably impacting a bit, maybe not much... But to be honest my concern was also about the working order the mount.
But don't get me wrong, I'm coming from a low budget asian mount and got the Mach2 about 2 months ago. It performs WAAAAAAAAYYYYYYYYYYYYYYY better, no question there. So there's the fact that I'm not very familiar with AP mounts limits regarding tracking and guiding yet. Had a handful of clear nights only. And I know my system is the challenging kind (mirrors, long FL, reducer backfocus, etc.)... So I just thought I'd ask for educated guess here.
Might also be PA as you pointed out. But I thought I did well since I polar aligned with RAPAS at the beginning of my session and refined with PHD2 polar drift align afterward. When I ran the Guiding assistant, I recall it was saying it was around 2-3 arcmin from the NCP... Do you think it's reasonable for my imaging scale (1"/px) ?

Please upload your guidelogs for this https://openphdguiding.org/getting-help/
Screen caps aren't enough information, but a quick glance looks like you have pretty bad polar alignment which would dramatically impact your DEC guiding
guidelogs would tell more
I wonder how much of an issue guiding is here - your overall rms is 0.49" and your image scale is 1.7"/pix, i'm guessing even if you addressed this you may not see a difference in your images
