EXP to MPR Calculation Formula (in General)

I searched the wiki and found this: MPR=(EXP/1.4307)^(1/1.2501)

So the question I have is this:

If I have 3 mil MPR and have 12 mil untrained EXP, can I plug my untrained exp into this formula like so MPR=(12,000,000/1.4037)^(1/1.2501)=341,098 and simply add that MPR to my total, or do I have to use my total EXP every time I want to calculate the MPR I would have, had I trained all EXP?

I think I know the answer, but just want to verify.

basically all that formula just tells you is the amount of MPR you will get from a certain amount of EXP. so just adding the found MPR to your present one will be fine

due to exponential nature that is incorrect. 2^2 plus 2^2 does not equal 4^2 which is what would happen if you just added. You first need to work the formula backwards from your current MPR to find your exp, then add the other 12mill and find out the new MPR.

Zog is quite right... that formula only works for your total xp and total MPR......

1mil MPR +1mil MPR does not equal 2mil MPR (or even close to it for that matter)

looks like i was wrong. maybe i should have actually looked at it a bit closer and realised it was raising it to a power and not multiplying. i don't know how i saw that. maybe should just go back to bed
