I am on my way to look at a 2013 pro rmk 600 155 for my wife. what should the compression be on each cylinder read? how much difference between cylinders is acceptable? is any bleed down allowable?

My '14 600 showed 80 psi (cold at 3300') when it was new. I thought that seemed low so I checked the gauge on my '07 600 and it read the same 90 psi that it usually does...I figured the low reading on the new '14 would increase as the rings seated but the compression was still only 80 psi at the end of the season this spring at 400 miles. I borrowed another gauge to check the accuracy of my gauge but it also showed only 80 psi cold ??
