I agree with this statement and along these lines, I have a question about the batteries. I am currently running a Ultra Low CG battery and they tend to have higher internal resistance. My current battery is running mid 4's for IR. I know this is high, but can anyone comment on how much this is hurting my power? I know a good battery has IR's in the mid 1's, but it's just one resistance in a series of resistances, so how much does the extra 3 mOhms hurt when the total resistance is over 30 ohms. So can I assume that increasing by 3 milli ohms only increases total resistance by .003/30.001 = .01%. Am I looking at this properly and if I am, then why worry that much about IR? I doubt if it is that simple.

EDIT: I guess a better way to look at it is to just look at the battery. If we assume we are pulling 50 amps under full acceleration, then the voltage drop through the good battery is 50 x .0015 = .075 volts. For the ULCG used battery it is 50 x .0045 = .225 volts or an increase voltage loss of .15 volts. This is a loss of 1.8% based on 8.4 volts. That seems a lot more significant than what I listed above. Guess it's time to get a new battery and to get a LCG, not a ULCG battery.
