Re: Fasteners extending outside the FRAME PERIMETER

The least nitpicky and anal retentive solution to this would be for the GDC to allow static (non moving) fastener heads to stick out no more than 0.25" from the FRAME PERIMETER, as long as they still fit inside the sizing box. This meets the spirit of the rule of the FRAME PERIMETER (it's not like having a button head stick out an 1/8" from the FRAME PERIMETER, but still within the NORMAL CONFIGURATION, will give that team magical super powers or some unfair advantage) while allowing leeway for teams that can't/won't buy flat head bolts and a countersink tool.

The GDC has been getting better about these kind of situations lately, with relaxed tape rules, relaxed pneumatic rules, etc so I'm hopeful this will be the outcome here.

If GDC is fervent that the FRAME PERIMETER means the FRAME PERIMETER and that means absolutely no exceptions whatsoever, not even for fastener heads, then this is exactly what we are planning on doing: just installing dummy bolt heads to redefine the FRAME PERIMETER. Fine, we'll jump through your hoops and sit and play dead, but we won't enjoy one second of it.
