I can't give fancy figures coz I don't understand what the fancy figures mean, but I can tell you how my mounts behaves.
This is using a Toucam and ED80, so it is equal to testing with a 6mm EP in an ED80 @ f7.5
The mount is a Skywatcher EQ6 running v2.5a
I have polar aligned by drift aligning for over 10 mins on each axis x3 times and get Zero drift (using crosshairs in Guidemaster)
On 3 star alignment, all 3 stars within 1/3 of centre of the finderscope camera.
After 3 star alignment, 90% of GoTos are dead centre of 6mm FOV, 10% are slightly to the side but still in the 6mm FOV.
Tracking is slightly erratic due to PE, but objects stay within about 10 arcseconds of centre FOV. Only once has it gone as far as about 30 arcseconds.
Guiding with GuideDog I was getting constant accuracy of within +/- 5 arcseconds.
But now Guiding with Guidemaster I get constant accuracy of within +/- 1.5 arcseconds.
Hope that is the type of info you are after.
