Its a bit hard to explain cause you have a lot of way to do it.
If you mean exp table (t_exp on your newproject_data) you can try with it:
UPDATE t_exp SET a_exp = a_exp / 10 WHERE a_level BETWEEN 1 AND 40;
UPDATE t_exp SET a_exp = a_exp * 10 WHERE a_level BETWEEN 41 AND 90;
It is just an example, with this query you decrease the exp needed for the first 40 levels and inccrease it * 10 for the latest 50.
Hope can help you
