Yes, i undestand both systems, i prefer the second, one thin we are using as reference by now is th ChairGun Bllistic Program.
For example, a friend of mine, uses three "different charts" the first setting is fron 7 to near cero at 10x. then change parameters ando go from, (as example), 11,5Mt to 32Mt at 24x, finally the las one from 32 to 55 mt at full zoom (32x i bellive).
seems too complicate, donīt you think?
btw, in the las 3 days... iīm sleeping 3 to 5 hours... the rest of the free time, i spend front of the monitor!!! my eyes look like this guy --->
