# How much experience does 1 MPR cost? (in General)

For the past weeks I've been wondering 1 thing, the Formula for calculating ones MPR based on experience is incorrect:

http://www.carnageblender.com/wiki/Various+Formulae#3

If I have to believe that formula:
4800 experience (400 levels) will increase my MPR with 661 points.
48000 experience (4000 levels) will increase my MPR with 4171 points.

Now we all know every level costs 12 points of experience to train, so this is hugely wrong.

Now I have conducted some experiments, with the thanks of Emotion so far for the 4 minion data.

On average, a 4 minion party gains 0.020463 points of MPR per point of experience.
This results in the Character gaining 0.245556 MPR per level trained on 1 minion.

On average, a 4 minion party has to train 48.86878 Experience per point of MPR they want to increase.
This results in the Character having to train 4.072398 levels per point of MPR they want to increase.

Now for 1 minion character data:

On average, a 1 minion char gains 0.013867 MPR per point of experience.
In normal training, this is 0.1664 MPR per level.

When a 1 Minion Character trains 72.115385 Experience, or rather 6.009615385 levels, it will gain 1 MPR.

Shade unless something has changed those formula are accurate within 0.2%....

The amount of exp required to add 1 MPR increases as the char gets larger so that is something to remember.

Then are those formulae to calculate your MPR based on your total amount of experience?

exactly.....

to see what your MPR will be after training you have to convert your current MPR to XP, add the new XP then calculate MPR

Ahh yes, I see it now. Those formulae are to calculate your total MPR or total Experience amount.

Then they are still right indeed.

However I would also like a way of calculating how much MPR I will increase when I train a certain amount of experience. We don't have one atm :)

there isn't an easy way to do so Shade...

Each XP you train means the next XP will add slightly less MPR.... so if you were to train 100k xp, the first 50k would add more MPR than the second 50k (even if you train all at once).

Converting your MPR to XP, adding XP, convert XP back to MPR is the only accurate way to do it.

Just make one really long equation that follows the steps Loch had stated and you'll have your answer.
