Doing full systems tests first flight of the day makes sense. Any full/partial systems tests for any particular reason on consecutive trip the same day - why not. BUT just because you run a systems test doesn't mean that the systems can't fail when a failure happens.
Most importantly - what the aircraft manufacture has written in the AFM/OM/FM should of course be followed. As a professional pilot one should know that he is not better than those test pilots who worked out the numbers and the engineers who constructed the systems.
If there's doubt - there's no doubt.
