At your weight, it may well be.
I’ll say this one more time: The ONLY way to know the best pressure to run is to start a tad on the hight side and drop a psi or two each ride until you start getting pinch flats, then bump it up a psi or two.
I guess the other way is start low and keep increasing pressure until you stop getting flats, but that could be a lot of flats.
