Opinions and experiences differ on this, but here's mine:
I don't exceed the max. recommended pressure - just to be on the safe side.
(having said that, I'm far from a super-heavy rider so I'm yet to see a tyre that squats much when I upload it to the max recommended pressure)
And I completely disregard the lowest recommended pressure.
(though, I'm usually heavy enough to not dare to go below that limit in order to avoid any pinch-flats)
I aim for about a 10 to 15 % drop in tyre height when I sit on the bike for the rear - and I use that same pressure for the front (explained with pics and in more detail here -
optimal tyre pressure).
