This is the spreadsheet with the calculations I used for the red tachy scale I posted earlier. Just like in the tachy image, I used 2 sets of angle figures: numbered major spokes in black, and un-numbered minor spokes in gray.
Angles in the first half of the table run up to 180° but the rest run negative for counter-clockwise rotation, since Photoshop limits rotations to 180°.
@kourosh . Got the Spreadsheet Thank You . You Guys are so smart coming up with the numbers in the first column . It would look rubbish if that was not right .
It took me a while, I could not focus to finish it. Left the numbering out so I can adjust it later.
These telemetry scales are all for 20 km/min, which is typical scale on watches (usual round number, even though it corresponds to sound speed at unusual conditions like 3°C in dry air).
