Cat, I see where your numbers are coming from, but here's a more accurate depiction of a fit for Assaulting (i.e. KILL ZEM ALLZ)
Cal Logi-

https://docs.google.com/spreadsheet/ccc?key=0AkNsTEpFxMxPdEZqV3MxSUprWWZrNDhaZFFTTGItQmc&usp=sharingAs you can see, for the majority of all the Combat fits (I went full tank here to showcase who the Logi abusers have been abusing the extra slots. Only the Amarr suits have equipment, and that's only a standard needle) of both suits, Logistics provide much more HP for lose of a Sidearm, and speed.
The Amarr Logi loses .24 meters per second. Every 4 seconds its assault counterpart is one meter in front of it.
The Caldari Logi loses .42 meters per second. Every 2 seconds its assault counterpart move one meter in front.
The Minmatar Logi loses .8 meters per second. Roughly every second its assault counterparts move one meter ahead.
The Gallente Logi loses .37 meters per second. Roughly every three seconds, its assault counterpart grows one meter ahead.
However, they have an boost of HP.
Caldari Logi gains 318 HP over its assault variant
Gallente Logi gains 245 HP over its assault variant
Minmatar logi gains 380 over its assault variant.
Amarr logi gains 167 over its assault fit, while retaining the sidearm and Equipment slots
While this may seem like a fair trade, considering that we can spawn 27K LAVs wherever the hell we want, the speed factor is made null. This tactic was, and still is by the select few, used by heavies to make up for their snail pace.
So, for all intents and purposes, the Logistic Suits gain 300 HP over its assault brothers, while losing speed that is used to cross the difference between the LAV parking spot and the Objective.
Balanced you say?
