# MPR Linear-e-ality (in General)

## Don't PanicMarch 19 2008 7:54 AM EDT

I was curious as to MPR and if it was linear or not. This came about from a discussion in chat, so I did a little research:

On a low level character I should probably retire:
Starting MPR: 281
Trained XP: 1,457,736
Ending MPR: 64,032
Growth Rate: 4.4%

Starting MPR: 10,424
Trained XP: 1,338,252
Ending MPR: 65,075
Growth Rate: 4.1%

And on my active character:
Starting MPR: 974,914
Trained XP: 53,736
Ending MPR: 975,869
Growth Rate: 1.8%

I'm not sure what this proves, or what I had hoped to learn, but I learned it, and since I went to the trouble of messing with it, I thought I'd share with the class ;-)

I heard sometime ago they already had a decidedly nonlinear formula for XP:MPR, before the rescale change. Anyone care to cough it up?

This number crunching was done just over a year ago....

I've checked my numbers since the change to 12xp/level and the MPR/XP ratios have not changed.

EXP = MPR*(1.4307*(MPR^0.2501))
or solving for MPR
MPR = (EXP/1.4307)^(1/1.2501)

I had promised Mikel that I would update that script... I never did. Sorry.
