Can't see the point tbh - as already said the rad cap will vent at a set pressure in any case.
Coolant works under pressure as it gets hot.
Not sure how you're gonna see the difference between head pressurising with combustion gas and water pressurising due to operating temps - aside from letting it cool down.
Arbitrary anyway, as will work at diff pressures depending on what ratio of antifreeze / water you run too.
