Both marks will force disc through the middle into the bowl. 2, 4, and 3 will take away the short middle throws. 6 will take away the over-the-top throw to the middle. 7 will take away the deep huck.
If disc is moved to break side, bowl shifts accordingly forcing the middle. 5 forces mark to the middle while 1 takes away the handler dump. 3 covers behind 1for the long throw to handler 7. 2 takes away the downline throw while 4 takes away the middle crash dump. 6 takes away the over-the-top throw to the middle and 7 takes away the deep huck.
If disc is moved to the other side, the bowl will continue to force middle. 2 and 5 cut off the other handlers while 4 takes away the short middle dump. 3 will take away the downline. 6 still covers the over-the-top throw to the middle and 7 takes away the deep huck.
If a disc makes it into the mid, the closes mark will force to the other marks side. 2 will shade down to cover the break handler and 4 will take away the break-side mid. 6 will come down to support the mid, still being more towards the back. 3 covers the force-side mid throw.
If 1 was closer to the disc, they will mark toward 5. 5 will take away the handler 1 leaving handler 7. The mids will return to their normal positions.
