MP at Level

i like this one much better because it looks like it accounts for the fact that a friend of mine went from 864 - 937 mp in 1 level with 100+ int. i was wondering about that inconsistency with the one i usually quote. it would account for gaining 8 mp at 20 int as well.
*shrug* better than 2-4.

For me, this is the one that makes the most sense. It makes sense, but I didn't think it would be so complicated to make it.

Code:

We set xy to a random number which is, or is between 0 - 99.

When you level and got xyz int (z is a number between 0 and 9),
you will gain (4 + xy + [0, 1 or 2]).

if z is 0, the chances for getting 0, 1 and 2 is equal.
if z is 5, the chances for getting 2 increases dramatically:

We will get a random decimal number:
from 0 up to but not included 3.

We add the 5/10 in, and the area we then get is
from 0.5 up to, but not included 3.5
that means there are 0.5/3 chance of getting 0,
1/3 chance of getting 1,
and 1.5/3 chance of getting 2 (because it rounds down.)
