definitely less than 10% and if you have gapless end rings less than 5%---if its a tight motor AND NEW never started you are going to see about 3-4 to maybe 5 - 6 %---watch for variations between the cylinder readings especially those cylinders that are next to each other-- not small ones like a few percent but big differences like 10-30%--FED 387
