Ok I think we all get that from a technical standpoint it was implemented correctly by giving it set values and such. But when it is actually in action, it fails.
The point I tried to make is that they didn't up the "randomness" of it enough if they wished to make it a core mechanic in the game. If someone is spamming, the should be able to hit the first 2, maybe 3, shots before the values under the hood get so crazy that they should literally have less than a 1% chance of hitting a single shot, let alone being able to finish you off by spamming. That's how the feature should work when implemented fully, not how it was when Reach was shipped. Anyone pacing their shots correctly should win more than 99% of the time, but that isn't the case with Reach and thus why people complain about it.
And for the record, I do spam close range or when I know I won't win a battle just because the chances of landing a shot are favorable when doing so in Reach.
