From measuring with my durametric:
The two that are to the left of the 200F are 170F and 190F. I was expecting a linear progression from the 120F mark to the left past the two evenly spaced ticks on the way to 200F, but they measured out as 170 and 190, then verified with 200 when I got to that level.
I have been treating the two on the right as 220F and 240F but when I was street driving with the durametric the time I did the calibrations I never got it hot enough to verify anything over 200F. And the two ticks to the left of 200F are not linear, so who knows
But if you look at this other VDO gauge that runs off the same sender (and this is an interesting thread as well)

The 180 and 220 marks on this cockpit gauge seem to match our VDO Vision Black gauges:
The 180 seems to split the two lines that I marked as 170 and 190 -
Edit: i just figured out to overlay the graphics, the 180F lines up with the 2nd line that I was calling 190F.
The 220 seems to line right up on the line I am calling 220
I have never gotten to the 220F on the street, the only time I get over 200F on regular street driving is if I get jammed up in traffic and not getting good airflow. On the highway it is 200F and below.
I also have a 180F low temp thermostat.
