given the fact that a stat may provide up to 5 flags

[uglyvan]

flags are 1,2,4,8,16;
say you have a score of 23 in a given stat, then you use 16+4+2+1

so, we may call
16 A
8 B
4 C
2 D
1 E

now if you have 7 stats ( MADEPPS for example )
then a flag climbs from 0 to 7

look out the fact that, for example
23 ( 1xA + 1xC + 1xD + 1xE )
is followed with
24 ( 1xA + 1xB )
then
25 ( 1xA + 1xB + 1xE )
etc

then, we must choose a function for the 5 flags ...
