Combat Medic Archive

Greetings. I'm a Master Doc and have been playing around with the resist buffs. I was wondering if someone could help me figure out what kind of stats I need on my meds in order for them to be effective. Is it as simple as....Potency - Resist Effectiveness with a min and max of 5%?

I looked through the FAQ here as well as a few other CM related sites I've been able to find and haven't seen the information I'm looking for. So I'd really appreciate any information you might be able to offer, or at least direct me to somewhere I can find it.

Thanks for any help you can offer.
