This is the site I use for lift angle data. 1° discrepancy equates to approximately 5° amplitude; if the lift angle is set too high the amplitude reading will be approx. 5° higher than it really is. Most watches have a lift angle between 48° and 54°, but the Omega co-axials are lower. Can`t recall exactly what the values are, but the different versions have different values. As ever, google is your friend.
If I come across something (usually old and lower quality) where there isn`t any data I leave the default setting at 52°, that's good enough to give an indication of whether the watch is running well or not.
Suggest you do some background reading around the subject, there's plenty of info out there.
Amplitude figures will vary depending on the movement. For an ETA 2824 or 2892 it's not uncommon to see over 300° in the flat positions fully wound, but on a 50 year old Omega 565 in good condition I`d be happy with 260°. If an old watch has significant wear and tear it's sometimes not possible to get the amplitude as high as it should be unless a lot of money is spent on replacement parts, you soon get into the realms of diminishing returns. Amplitude figures are helpful when assessing a watch but other factors have to be considered too. I`ve seen old watches that are filthy inside yet the amplitude is good, sometimes the oil dries up and the pivots are running dry which ironically gives good results, but the wear rate on the pivots will be accelerated.
Learning how to interpret the traces is all part of the fun too!
