Gary,
I believe, as you suggested, that the FRAME PERIMETER in the strict definition is the outside of the frame including any fasteners in the bumper zone. It is those dimensions that would also define the extent to which fasteners and other parts can extend out from the robot body because that now defines the NORMAL CONFIGURATION. I think it will be fairly easy to tell with the robot in the sizing box with no bumpers. As the rules allow clearance holes and pockets in the backing of the bumper (R07, D), I believe the GDC is allowing the fasteners and therefore the FRAME PERIMETER to merge with the inside of the bumper as they have in the past. Depending on individual design, it may be necessary to have a team rotate their robot to test all sides to insure compliance with these rules as the sizing box really has only two solid sides.
