Interpreting timegrapher results

[Blueteg]

I just purchased a Weishi No. 1000 timegrapher and was hoping I could get some feedback from you all on the results.

The watch I chose to test is an Explorer 2 (ref. 16570) that I purchased about 2 years ago. Love the watch and it keeps decent time, but I purchased it with unknown service history so I was curious to see how it would perform on the timegrapher.

Before starting, I read the article on Bob's Watches about the timegraphers, and the author of that article gives some ranges on what he considers to be excellent vs. acceptable.
For amplitude, he states excellent @ 270 - 310.... and acceptable @ 250 - 270.
For beat error, he states excellent @ 0.0 - 0.5 msec.....and acceptable @ 0.6 - 1.0 msec.
Thoughts on those values/ranges?

I started off by winding the watch to 50 clockwise "turns" of the crown. Closed the crown and set the watch on the timegrapher. Next, I set the ramp angle on the timegrapher to the ramp angle that I found online. In this case, 52 degrees for a caliber 3135. Last I set the time interval to 30 seconds. It tested the watch in the usual 6 positions and let it sit in each position for about 1-2 minutes to make sure the movement was settled and the machine was producing repeatable results for that position. I've included a table with the individual values for each position and the average over all 6 positions. Your feedback on the measured amplitude and beat error, is appreciated. TIA
