Ooof 40 and 80 are really bad. Bad results wet would point to broken/pinched ring, but if your really lucky a sooted up ring. I used something called b12 chemtool in my cylinders when I got the motor. It had been sitting outside at the previous owner's place and got some water in the intake. To my surprise it cleaned up perfectly and had 135-140 compression on all cylinders. Valve sticking would be very obvious to spot with the valve cover off, you would see a valve noticeably lower than the rest, unlikely to be the issue though.
