TSX Accurate Polar Alignment... What am I doing wrong?

Taken me a few attempts to get used to new software, mount, telescope and camera. Taken on everything all at once haha

Was doing my first T-Point iteration last night (~60 stars) and did the Supermodel. It said that I had to move ~105 arc minutes East and ~30 arc minutes up. Started the accurate polar alignment routine, slew to Acrux, centred it and then pressed "Commit". It made this massive slew (relative) wanting me to lower the mount ~10 degrees and move ~15 degrees in azimuth. I started on it thinking it knew what it was doing, went this is stupid, pressed Done, parked the telescope and then slew back to Acrux l, re-centred Acrux.

Did another 60ish routine and got down to ~3 arc min below and 12 arc min East. Did the Accurate polar alignment routine again, over corrected the elevation (5 arc min overshoot) and had me move ~12 arc min West instead of East.
I found the above out after doing another 60ish model, had to move 5.5 arc min down and 24 arc min East. Just ended up guessing it and left it there.

What am I doing wrong?
