It's not <R08> itself--it's the Q&A responses. They are being VERY repeat VERY strict about deviation from the designs in <R08>. No lightening holes, in fact no holes other than mounting holes, are allowed (by Q&A). Also, no single-pool-noodle-high bumpers are allowed; that's been asked too. You've got it single-high on teh corners, and you have (presumably) removed the backing for weight. That's a mighty big hole... and it isn't for mounting purposes.

Again, it's Q&A about the rule, not the rule itself. There are three pages on robot safety. Almost every post is about bumper design.
