Jeff,
First, before you get to Tom, you need to go through me - an ex-brewery advanced workshop instructor!
Second, other than your warehouse test and statement about "all systems do this", most of what you claim is understood quite well. Even by the technicians who believe and practice the 70% you claim is worthless.
Your systems may have issues with breakout and foam. The systems that Tom and the rest of the staff at MM have designed and/or installed seem to be performing just fine while protecting the product from the keg to the glass. If you want to start a debate that would be worth your while, pick on those gas company reps who continue to spew there crap about how great the beer gas is for retailers.
As for mctripj, what is the temperature of the glycol chiller bath? When you state that the glycol is split at the towers, it it looped or are the lines "T'd"? Third, have you performed a flow test? Last for now, have you performed a leak test on the pressure system?
