You want something in the high 90% area. Depends a lot on mileage/condition of the motor, ect.

you want the lowest drop in the percentage. you typically want between 100%-96% The drop in percentage is the amount of air you are losing. for example 100% means there are no leaks. 98% means 2% of the air is escaping the cyclinder tested. anything more than 4-6% is a big loose and you want to look into it. This is coming of the top of my head, but i believe those numbers are right.
