I've attached a picture of our .75" plywood bumpers from when we rebuilt them after MAR champs. As you can see, there's a large crack down through them. Why do you think our bumpers broke and your frame will hold up?

It's not about the strength of the material as how it's used. It looks to me like there's a lot of your bumper which lies above any backing support, which means that the plywood only has its own thickness for strength. In comparison, look how every panel of his frame is supported at the top and bottom, with many ribs which support it continuously. Plywood (and most sheet materials) are much, much stronger when loaded in ways that compress or stretch pieces rather than bend them.
