I don't think it is specific to larger blades. Flex is a big part of why Dino designed/built his smart table. Here a while back (it is in this forum somewhere, more then a year ago), I was using my 7 1/4" saw, and caused myself to pinch and flex the blade. It pinched it to the point the blade spun loose under the nut (had to be retightened).

In that case, I would look for anything that could cause the material to pinch the blade. Screws, nails, scraps, etc. riding under the plywood and forcing it up and into the blade (would end up with not square edges as well).
