The best I can say is that it made the wheelbase longer than required to account for one tooth less off the front sprocket. The adjuster re-shortened the wheelbase. Unless I'm missing something, the point is moot that the flip equates to a specific number of rear teeth as you will need a longer chain to increase the size of the rear sprocket. Consequently, It's your chain length that will dictate which way the axle block will go to minimize altering the stock wheelbase once you increase the rear sprocket. If anything, the block flip equate to a specific number of millimeters lengthening of the wheelbase."Does the block flip equate to a number of teeth?"
Welcome to the question, I too "Believe" the flip would be adequate, but is there a number of teeth? It's ok that you don't know. I though maybe there is a maybe someone out there that is swapping sprockets and might share some insight. It would be a nice perk to be able to do quick change sprocket carriers and the flip the blocks and get back on the track, perhaps run a 45 on the OEM wheels and a 44 on lighter wheels. Also curious how thoughtful the engineers and designers, surely they didn't just pull a measurement from the butts.Post edit:
Following further reflection in practical terms, If you were to have a chain length that would accommodate a 45T, I believe that flipping the axle block may be sufficient to pick-up the slack when quick-changing the rear sprocket to a 44T.
