Supercharged mounts with 4-5 times better PE than normal

I was reviewing mounts with acceptable carrying, pointing and tracking capabilities to handle long duration astrophotography.

The CGE was looking interesting until I saw its raw PE is around +/- 15 - 20 arc seconds (ugh), so all its great looking design and asthetics, and its simple to use functionaility it looks like it fails the tracking test badly.

Interestingly I read about Dr Clay Sherrod of Arkansas Sky Observatories who does a 107 step "supercharge of mounts" like the CGE. The results seem to be PE of 4-5 arc seconds - or better with PEC!

I wonder if there is a service that can improve PE by 200% - 300% - why don't Celestron and Meade do it out of the box as part of their quality assurance program?

Anyone experienced this?
