Camel Fiddler

I used my dash display earlier and the gauge to check my car warming up. The needle moved off the bottom at 45degrees and hit normal at 60degrees. On a 70mph cruise it showed 94degrees once warm but coming off to a slip road it would be 90 or less by the end of the slip road the temp seemed to drop so quick. In a 30 zone it's about 88degrees but shoots up on acceleration.

Is this all normal?
