Issue with cost calculator

[thatguy96]

Hi, just wanted to say its an amazing job as usual. It looks like WinSPWWII has added even more helpful features and the gameplay can only be better than that of WinSPMBT.

However, I've noticed something I don't understand with the cost calculator. I tried to create the T34E2 version of the T34 calliope rocket launcher in the US Army OOB. The only difference with this version was that it used the more powerful 7.2" rockets. So all I did was copy, change the weapon numbers (to whatever it was for 7.2" rockets, noted from the M17 RL) change the dates (saw limited usage during 1945, so I set it just to 1945), and when I run it through the cost calculator it says the cost should be 10 points LESS based on the ammo factor. This just doesn't seem correct to me.
