That seems logical, but I wouldn't worry about it all that much.
My Focus has the opposite problem - it is supposed to have a CHT and no coolant temp sensor according to Haynes, but UG shows 195-235 on the CWT gauge.
But I bought the UG mainly b/c the analog gauge reads right in the middle except one time that the fan resistor broke and the gauge read "a bit hot".
I found out
the Low speed fan should kick in around 225-232 and the HSF should kick in around 240-245. Based on that, I left UG at 250, but I'll probably watch the analog gauge and if it gets hotter than I think it should be, I'll probably set the alarm for that reading (or 250 - whichever ends up lower). I've had the UG for 3 days and have seen 236 on it and the analog gauge was dead set in the middle.
The above is probably the best for you as well.
