No, imk2 is a "never" weapon. The difference is a definition on 0->100 for function A vs. three different functions. One is 0->47, another is 47->52 and another is 52->100.
(i will presume that mako starts at 47 and max at 52, sorry if is silly, i write in a bit of rush didn't check actual stats but you will get the point).
A "never" weapon would behave at lvl 100 as mako would, if my numbers are correct, at lvl 52+.
BUT a mako lvl 0-47 would behave much worse than a "never". And for lvl 47-52, situation is very arguable.
Not the last, you're talking an imp wep.
I would presume a more relevant log (for this thread particularly, in no way denying the usefulness of your data) would be, say, ep-41 military vs., say, an equivalent (L) in terms of ideal dps, dpp and decay.
