Is heater core clogged?
I'd check that first.......

That's where my 90 runs is just a touch above half way on the gauge, perfectly normal.

After I replaced my 180* thermostat back to a 190* that is how mine runs as well. Guess it is normal but it kinda bothers me too.

stop going by the factory gauge, go buy a real mech gauge so you can know what temp the engine runs at and not just a generic "runs at half gauge"

reason I mention this is more often than not the factory gauge is less than accurate expecially if the IC voltage reg is bad
