Coolant Temp

[SlayZombi]

So since I have never had a "normal" temp since I bought my '01 Saturn, I thought I would ask here if what I have is now normal. When I bought the car I had very strange issues with RPM fluctuations and the temp needle never went above a quarter. I changed it (it was indeed OEM and cracked at the tip). High RPM's and fluctuations are gone but the temp usually doesn't go above about a quarter. 2 days ago I did a coolant change (full) with fresh Dexcool along with changing both the bottom and top radiator hose AND the thermostat while I was at it. The thermostat said made in Germany so I imagine it was the original one from 18 years ago. The car runs great still but the temp now seems to have settled at about a quarter before the halfway mark. It doesn't go higher than that so I am curious if that is actually what the real temp is supposed to be at when it's "settled" into original spec operating temps. Could it have been possible that while the old thermostat was still working it was leaking? Or is this new temp too high and I messed up somewhere?
