Extra math work is pretty cheap compared to the cost of a spacecraft and
its booster.
A real-world example of this occurred in the Soviet space program.

It's a very nice real world example, other than the niggling detail of
having exactly nothing to do with the real world and only being
relevant to the nonexistent problem you are handwaving into existence.
You seemed to have missed that the different centers have different
software _because they have different needs_. A Shuttle will never
crash because JPL neglected to check JSC's results. A Jovian probe
will never miss because JSC neglected to check JPL's results.
