Ok ... so discovering this myself I’m posting it here so if someone else needs it and does a search they might find it here... 

There are 270 teeth on this ring. The setup was down inside – in air conditioning. 
Green Heron Control box RT21 set up for 24VDC. 
The pot is 500ohm... centered on 250 ohms. 
- the low side, -135 tooth count in one direction so 180° is 58ohms. 
- the high side, +135 tooth count is 442 ohms. 

That leaves roughly about 62° before ‘damage’ so a good bit of leeway assuming properly set up this way. 

The GH is easy to calibrate in the house using a DC supply and an ohmmeter. Dead nuts on 000.1 when done at the center point.
