Rick,
I run my mount tracking unguided on Sidereal for a minute or 2 and can still get decent star shape
After 30 minutes it’s only drifted off the bullseye at 2 x zoom on BYEOS a small amount
So I think sidereal tracking is sort of ok , but polar alignment plays a big part too

My guiding error on most nights with the HEQ5 is 1.20 to 1.40 arc sec
I’m finding that dithering is knocking the DEC around a lot and recovery / settle is taking up to a minute even on a low Dither
I’ve never got it down to 1 arc sec or below
Most posts I’ve read where members have done the Rowan belt mod and / or bearings etc are guiding below 1 arc sec error
Your balance and payload is a big factor as well, I’m carrying a 6” f6 newt , DSLR, guide scope , finder scope , dew heater bands etc.....so roughly about 9kg , so my payload is up there ( it should really be no more than 7.5kg on these mounts )
