Hey folks, Just doing my QC checks with Andrew, could anyone offer insight into what info the machine in the below image is providing?

Also, are there any specific checks for flaws you guys have requested before? Anything I should look out for? Think the QC pics look good, but I’m inexperienced at this.
Thanks a bunch
1. The accuracy is spot on at 0 seconds gained or lost per day in that position.
2. The amplitude is 316 degrees which is on the higher end of where you want to be (around 250-320 degrees) but looking at the line you don't have knocking so you're good on that part. If the movement was knocking you'd see the line being broken up by snow as the balance knocks and resets itself.
3. This is the beat error at 0.4 which is fine. It measures how long a tick takes in regards to a tock so to speak when the balance spins. 0.0 is the best but up to 0.6 is acceptable for a new watch at this price point.
4. This is your beat rate which is 28800 vibrations per hour which translates to the seconds hand moving 8 times per second. A real Omega coaxial runs at 25200 VPH but that's not something that is replicated anywhere.
5. The 12s here I'm not sure about but I'm guessing that's how long the timegrapher has been running
6. This is the lift angle of the timegrapher. You set this number according to what the movement needs to be measured at.
All in all a good result.
