Ranged Attack Class DPM

As response for your first statement, my simple defense is to find where my math is wrong, then tell me I'm on crack. I am open to any correction, but trying to invalidate my math using a flaming statement derived from a subjective observation generally leads to no avail. To directly answer you question, contrary to popular belief, NLs, even with SE still don't have an exceptionally high DPM, only with Apples do NLs really shine. An NL with SE is still weaker than a BM, which is already known fact, as BMs have far more weapon attack as well as support skills that together, far outweigh the ability of TT. MMs unappled have a higher DPM than BMs in early and mid 4th job, so it really is to be expected that MMs DPM is higher than NLs + SE. Grated there are a number of other variables that can come into play, but I really fail to see how this comes as such a surprise to you.

The math itself isn't wrong, but as the three posters above me mentioned, you missed some very important things which make your numbers incredibly unrealistic. I have personally beaten similarly leveled Night Lords in damage with my Bowmaster, so I'm well aware that they're nothing special until they're tricked out. But really, you should have rechecked your setup if Marksmen came out over NightLords, because everyone here and ever calculator disagrees. Aside from the fact that good gear helps Marksmen less than most classes and helps Nightlords more than most classes, there's still Snipe and its horrible cooldown. Every bit of math ever done shows that Marksmen would be pretty crazy if they actually could shoot it every 4 or 5 seconds, but realistically it's something like 7 or 8. That's why I try my best to emulate realism by putting a cooldown modifier in both my Corsair calc and the Marksman calc I made for Carlos. I don't know what situations these numbers could be used for, but they seem to be pretty far from any real situation I've run into.

Damage per Strike

I have never heard this interpretation. I don't think your car analogy applies since neither of us are doing any estimation or bad rounding like the people who use feet. I guess it really comes down to preference. I find the large numbers ugly and harder to compare and use for calculations, and I've been using DPS for such a long time that DPM is pretty foreign to me. They're still essentially the same numbers, one is just divided by 60.
