Yes Craig, no one is arguing about that fact, but arent we discussing, shrinkage when cleaning a carpet, which will not be as substantial as when a carpet is flooded. Also the more the yardage the more carpet to shrink and the greater the force.
Anyway Chris, as you started this thread, take what you will from my comments and if you think someone else has given you more of a convincing answer, then take theirs and ignore mine.
Dave.
