I nearly finish my gear calculator datafield. Yes, there is already some, but non of them know what I like.
One of my idea is save the calculated front and rear gear information into the FIT file for a late analize or whatever. But the graph can show only one number, and I am not sure, what is the best number. I ask the AI 
and it suggested that I thinking about earlier, so not better idea.
Let see my possible ideas for the numeric value:
Combined total speed gear like on a 2x12 system a number from 1-24. Maybe ordered by ratios or simple one chainring&cassette gears after the another.
Its good, when the calculation is jumping between the chainrings (the ratio is fit for more combination) there is no big jump here it ratio ordered but there is no visual information about when I change chainring.
Gear ratio Float number. Also nice continuos shifing even if the ratio jumping, but there no information at all about the real shifter position. Maybe a 3th part program can use it and count back to chainring&cassette position.
Combinated chainring&cassette position in one number. What I mean, the 101 means 1. chainring 1 cassette. 309 means 3. chainring 9. cassette. etc.
Combinated Ratio & chainring&cassette. Just like before but add the ratio like ratio*1000 . chainring&cassette. e.g.: 125.205 means 1.25 ratio , 2. chainring 5. cassette
What you thing about it? Maybe a better idea, or what is your favourite from them?
