I don't dial for wind.
I hold off
I generate a local click card which gives me the wind hold-off (in inches) per 5mph per range.
It tells me how many elevation clicks to dial per range, based on actual click value (not merchandised value).
With laser ranging this system has set my GH accuracy capability to 500-650yds.
A couple of my guns have been accurate enough to extend that -with V/H Coriolis, Spin Drift, and slope.
But I like the little card w/ranging binoculars only. It's simple, and stalking is hunting.
Perfect for me is a simple med-fine crosshair at 25x+.
As far as IPHY, MOA, or MILs, I take it to clicks, so it doesn't really matter.
1/4 clicks seem good enough for IPHY/MOA. I don't know what I would need for MILs.
Unless the scope is in IPHY you are just messing with yourself and making your life harder doing anything in inches. I don't dial wind either but all my wind data is in the graduation that my scope is in. All mine now are mils so I know how many mils I need to hold for whatever wind hold. If I had MOA it would be in MOA. I need to hold 2.4 mils left then I hold that. Not 24 clicks as there are no clicks in the reticle. Or inches. Same with MOA reticles that I have used over the years.
Clicks is just a waste of brain space to me trying to figure out how many clicks I need to hold seeing as my scope reticle isn't in clicks. When using inches and clicks you are doing multiple conversions.
Your set up though but if you wanted you can try some different ways to see if it actually makes your life easier.
