The gauge starts at 40 and goes up to 160.
I would say it stayed at the second mark up half way to 100 (which I'm guessing is around 70 degrees?) ie halfway between 40 and 100.
Just started her up this morning to take another look and the needle sits below 40 before starting and has moved up to just over 40 after a 15mins left on tick over.
I guess I had not really noticed it before but thought perhaps after a fairly good run it might have been higher than the second mark? The needle is at least moving!
