A tentative integer-valued birational invariant of threefolds

I will give an experimental evidence towards the existence of an integer-valued birational invariant of (rationally connected) threefolds, that tends to distinguish most Fano threefolds with Picard number one. Also I will describe what values it should take on some known examples, and what properties it should satisfy.
