Stealthee: I posted a pic over in the "thermostats" thread. For a GP with a 195 stat and Ill post it up here too, the middle mark is not abnormally high. The middle mark is approximately 210-212. At idle, many GPs 04 and up go to the first line past the middle mark (221) before the fans kick on and bring it back down to 200.

For someone with a 180 stat cruising range is between the first and second line past the quarter mark
