temp gauge question

[Day 2 C10]

So I took out my c10 for the first real ride of 25 in its winter tune up. Truck did great no issues just a question as I have a 185 t stat in it (better winter heat) and sitting at the stop light it climbs up to the pictured reading and hangs around there for the most part. what dose this area correlate to on the temp gauge for temp the sender is in the drivers head and the mechanical gauge is in the intake that reads 180-190. I just want to make sure as the gauge in the summer hangs out in the middle with a 5/8 restrictor no t stat
