Sorry, I needed to be more specific. I was wondering about the degrees of rotation on the parallax turret. The higher the degrees, the more precise you can use in measuring for HFT distances. In HFT, the highest magnification is 16 and you cannot move the elevation and windage turrets at all, only the parallax turret. In this case the higher the number the better, giving you more "indexing" granularity on a large focus wheel.
