Thank you Rob01 for proving my point: That the MSR reticle is much easier to use with simple hash marks at .1 milradian intervals. No half circles, hollow circles, hash marks and such. You just line it up and read the reading. One interesting fact is that getting these readings accurately while laying prone is a challenge. With rifle movement, even the slightest, throughs off everything. The MSR reticle, being more simple, allows for a more accurate reading. I sometimes get within 1-2 meters of actual distance. The H2CMR is a great reticle, an improvement over the original mil-dot, but more complicated than the MSR. While it took procovert45 two lines to explain the ranging function, it took you several pages.
