Join the new world

Well, I'm not quite a talkative guy in this game, but the rising version has been consistently confusing me, so I have to turn to you guys for help.

What I'm gonna talk about today is the military formula. Since the new military module is not formally launched yet, I looked up the equation on eRep Wiki. Here is the link:

The damage D = ((1 + (S - 1)/10) × W) + R, where S is our military skill, R is some neglectable random factor, and W is our weapon damage. Assuming we are all using weapons with maximum ammunition, W is 10 for helicopters, and 14 for tanks.

Then after some calculations, I came up with a conclusion that puzzled me a lot.

The damage of a heli veteran(skill 10) can't even match the damage of a tank sharp shooter(skill 5)!

Think about it this way:
One has been training with the highest booster every day for almost one whole year, yet his damage can't even match the damage of one who's been training for only a couple of days?

I'm not good at mathematics so someone please tell me who is wrong, me or the headless chicken?

Oh, right, air units have +20 attacking points against tanks. Score! +20 attacking points equals to about 8% higher attacking rate. What a great advantage!

Now, are you still gonna spend your time and money training heli skill?
