No they're not. This is the same logic that Feynman slams when the

Of course in this case we are talking about a motor for use on an unmanned vehicle. The SRB is a whole other ball of wax, and expected to have a far higher level of reliability, even if that means overbuilding it to gain reliability at the expense of performance.
