4. B motor version MIGHT have had a much higher cato rate?

Not saying they did, but that is another possible reason.

IIRC the MPC B size 13mm Mini-Jets had a significantly higher cato rate than the smaller ones. Though it may have been one nororious bad batch and they didn't make that many batches of B's (or the others) before MPC bailed.
