Thanks for the responses - they appear inline with our thinking. We understand that the lower edges of our bumpers probably need additional support. We needed to understand the intent of "fully supported" better before we complete the design. The 1/8" aluminum on standoffs answer created more questions than answers - clearly bumper strength depends on quantity/placement of standoffs.

Bumper corners remain problematic. R08-N clearly states: "“Hard” parts of the BUMPER (i.e. plywood backing, fastening system, and clamping angles) may extend up to a maximum of one inch beyond the BUMPER PERIMETER." and then the figure 8.4 shows a ~3/4" extension as not ok!!

R08 does not seem to include any words that state that corner reinforcement of bumpers is allowed or disallowed on the inside surface. I guess the safe thing is to attach the corner reinforcement to the robot frame.

re posting to the First Q&A forum - yes, I was trying to post to the response forum - I will go back and try again.
