onovakind67, youve been on steves nova site havent you..... i got into an arguement with a guy about this over there, he liked to ramble on and on with his fancy terms and it seemed to me like he was trying to impress someone. The fact of the matter is, "bleeding off compression" is a term that is very commonplace among enthusiasts. BUT for the guy who dosent understand swept volume, volumetric effecency, and all those fancy terms. Its a simple way of saying all of what pat just said. Call it a slang term, maybe not proper, but slang. Anyone ever... "bang some chick" or did you, as my boy Mike Tyson likes to say.... "Fornicate"
