Charles,
I think sometime let their  mouth get ahead of their brain and make dumb 
statements I have done a lot of  compression test as per the book. You are 
supposed to do one dry then another  wet (adding some oil to the cylinder) to see if 
the rings are holding A higher  reading with oil would tell that they are not. 
If its low and the oil doesn't  bring it up then its most likely in the 
valves. 
But always start with dry  cylinders so that you have a good starting point 
to work from. OH! remove all  plugs or injectors and let the engine spin good 5 
times to get the proper  reading. And check that against the manual not what 
some clown thinks it should  be. A proper compression test is not just a hap 
hazard thing and if done wrong  will lead to poor readings that will only give 
bad information.  It doesn't  take a minute to lookup how to do it on the net 
there are lots of websites that  will help you.
