The total peak to peak error
is just under 10 arcsec's, with no Periodic Error Correction, very
good for a mount in this price range. The result should even better
with the Gemini Level 4 PEC applied. Instead of the desired smooth
"sine wave like" curve, this worm gear has two peaks with three
valleys, with a few bumps along the way. This is all easily
corrected with auto guiding.
Improvement may be achieved
by swapping the DEC and RA worm gears. Also, one can buy a new gear
for $50, hoping to get lucky and receive a really good one. Another
improvement is to use higher precision bearings.
