Thanks for that Dan really appreciated. I wrongly assumed the PC platform was also linear when using ShotPal.
I just thought I would make it easier for myself and develop the 'Sticker' for my iPad. I decided to plot each of my clubs at the linear %s and graphed the data in Excel. I then fitted 2-part polynomial curves and what I noticed was that they all performed to the same non-linear fashion so hence the development of the non-linear Sticker.
However, one still has to hit the 'Ding' whatever we 'dial' in.
Cheers
Yours
Andy
