Yeah a lot of people think the H59 is busy, its all personal preference. I can see how someone that has time to study and shoot with the tremor can benefit from it. The biggest problem I had with it is the wind dots each dot is a different hold depending on the caliber. For example I think for a 5.56 each dot is 3mph and for a .308 they are 4. So I can see how you can make quick adjustments with it but if you know your rifle you can make the same call with typical milling. One thing to keep in mind about the wind dots is if you dial any elevation it messes them up. For every 5 mils you dial they get cut in half.
They spaced the mils unequally to aid in distance estimation which is something I haven't even began to touch on in my shooting. They tell me the 2 farthest berms are 750yds and 1000yds so I'll trust them on that.
Check out snipers hide that was the only place I found that had any sort of explanation when I was looking into it.
