Follow up to my Watchtimer

[hsfrank]

I am a newbie using a watch timer. I got my ace timer and have been using it on my Rolex watches and tutor watch. As an aside, Rolex advised me that the lift angle on a North Flag is 49 degrees. Now I have two questions at this time.

On the timegrapher, The top line lists the Parameters, the next line has the results. But is the line below that with values that I do not know what it means. I would appreciate someone advising me on that .

With my wife’s Lady Datejust although the loss of seconds per day is fairly consistent across all six positions with minor deviations ( varying from +3 to -3 )I am getting low ratings with regard to the amplitude. The reading is between 240 and 245. Is it correct that readings of 250 and above are acceptable? Does this indicate a need for service?

Thank you
