Subject:      1982 Air Cooled with compression 110, 110, 115, 115

Hi Guys,
 
I just did a compression check this weekend and it seems almost too good
to to be true - 110 lbs in the 2  forward  barrels and 115 in the rear
2.  
 
The engine has not been torn down recently -  I think it has about max
50,000 kms  (30,000miles) on professionally rebuilt engine done in 1996
including new cylinder heads.   (  I can't tell exactly how much
mileage... from my records the odometer was broken for 3 years)  

1.      got engine up to operating temp 
2.      removed all plugs 
3.      put in the compression tester 
4.      let the engine turn over about 4-6 times 
5.      repeated on all cylinders

All 4 of my month old plugs have consistently grey white tips but the
ceramic around is black.    
 
So my question is....did   I  skip a step that skewed the results or do
I just have a strong engine? What do you guys think and how often should
I do compression checks to verify the state of the engine?
 
Thanks
