help with composerate

pets at first take 4point and keep go up until it reach 1* and 20 points
i need to fix it and make it 15-20 :(

UPDATE `cq_eudemon_rbn_rqr` SET max = max * 2;
UPDATE `cq_eudemon_rbn_rqr` SET min = min * 2;

Run this a few times untill you get the compose rate to where you want it ...
