"Normal" Temperature Operating Range

I have a 3.0 and I'm trying to find info on the "normal" coolant temperature range. I put my scanner on and drove around for awhile. Around town the temp varies up and down between about 192 and 204 with spikes to 206. When I jump on the freeway and get up to about 80 mph the temp drops to about 180. The first time I checked this it dropped to 176. The temp then fluctuates between 180 and 190/192 while on the freeway. Is this normal? Seems like the t-stat is allowing about 20 to 30 degree variation. That seems pretty big to me, but I'm no expert.
