As for your scenario where there is a turnover on downs, the ball is to be placed exactly where it was at the start of fourth down and the l.o.s. moves from one end of the ball to the other on the change of possession.

Dave, either not comprehending what you wrote or one of us is wrong. You say "in this situation", which seems to imply that in "other" situations the ball would be moved following a loss of possession on downs.

Am I reading you correctly?
