do you mean 90? if its at 9 im pretty sure its toast... but if you mean 90 then it is acceptable but probably on its way out the door if i recall. you could search "compression" and you should be able to find a bazillion threads dealing with compression

hmmm, i assume they mean 90 which is medial but i wouldn't put $1150 on an assumption, i would contact them.

p.s. about 110 is like new and 90-100 is good and anything under 90 is probably on its last legs or headed that direction
