ok i wil give you a slightly more define answer
you first off need to know that your mastery lvls and you player lvl are directly connected.... so the closer your 2 lvls are to each other the more evenly the exp and sp will be distributed. if you are 2-3 lvls ormore lower in your masteries then you player lvl you will see and pretty big increase in the amount of sp per kil you get. so if you arent too worried about lvling at the time and really want to grab some sp, hold off on lvling those masteries and just accumulate a bunch of sp . i/e/ farming
hope this helps you understand the technical aspect of it a little better
If you have you highest mastery which is for example, 15 and you are 9 levels above 15, in this case 24, then you will gain max sp exp possible.
