I have been imaging for a few years on my G11G with my 150mm refractor @1050mm, with a total weight of 24Kg on the mount.
I believe it is very close to the mounts limits, but doable.

I could achieve 0.6-0.7 consistently, but it took me quite a while to achieve:
- the obvious, using an OAG, perfect balance lowering alt to as close to zero as possible and "3 positions" balance (rough RA/DEC balance to start, then scope "rotation" balance with the scope pointing at zenith, then DEC balance with the scope horizontal, then RA balance)
also matching counterweights to get them as close as possible to the center.
- mechanics should be fined tuned and grub screw adjusted frequently. I find that doing that requires some finger feeling: So by hand I tighten the grub screw until I can just feel it touched. For the spring tension Brian's (Valente) specifications are just perfect.
- One thing I did that might help is I moved weight on the back of the scope using the 24" dovetail and having my Intel NUC sit on the back. I did this to be able to passthrough the meridian without hitting, but it does reduce the arm momentum.
- Not sure how much this helped, but I also got my cables "through the mount"

Now for your RA specific issue some guidelogs would be required to trace the source of the issue.
