This is the problem:

[R27]
Robots are required to use Bumpers to protect all exterior vertices of the Frame Perimeter. For adequate protection, at least 8 in. of Bumper must be placed on each side of each exterior vertex (see Figure 4‑1, Figure 4‑2, and Figure 4‑3).

You can't count the material in the corner - you need 8" on each side of the exterior vertex of the frame perimeter. That means you need 8" of frame with 8" of plywood and 8" of pool noodles and 8" of durable cloth covering in front of it. That is the absolute minimum length a bumper section can be when attached to the corner of the robot. It can be longer - you can have another 1" of plywood hanging off the end of the frame perimeter (R28B), you can have "soft parts" of the bumper extend another 2.5" past the frame perimeter (R28C), and you can extend the bumper further down the frame perimeter away from the vertex (you can even have the entire length of the frame perimeter covered in bumper if you want!).
People keep trying to lawyer this rule, and have been for a long time now... it's written clearly, and your LRI will tell you to fix it if you have 5.5" of bumper with 2.5" in the corner - argue all you want that it meets the requirements for R27, you won't get your sticker until you fix it.
