Instead of forcing one direction or line-trapping we force middle of the field.
Same as a normal cup with mark being the same unless called otherwise.
Disc swings and mark changes.
We are hoping to force lots of swings which should sit up and float in the wind for easy ds.
Reset with disc in middle.
Wings need to be super vigilant/active as there is going to be opportunities to grab the disc if it is floating.
Reset with disc on the sideline.
If middle handler moves back then the 'number 1' person in the cup may move up (to a point which is no more than parallel to the person with the disc. If this occur there is a fairly obvious gap in the cup so it is the middle's job to fill the space.
Once the disc starts moving again short deep drops back into position until he/she is required again. (If on the other side then the 'number 3' player will move).
