Not real bad but you will have more loss in time. It isn't uncommon to have a bit less compression on the rear cylinder with the mileage you have. The extra heat the rear cylinder has may contribute to compression loss over time.
Did you check to see if the rings are the problem?? Squirt some oil in the rear cylinder and do the compression test again, if the compression increases than the rings are bad if the compression stays the same than it is the valves that are leaking.
Both are a easy DIY fix.
