I am not angry or offended at nature. However I do not like to see people give inaccurate advice. The evidence you provide is (and always has been) based on your observations of bonsai trees. If a VFT was a bonsai tree then I would not be discounting your advice. The problem is that VFTs are not bonsai trees. They are not native to a climate where they expect sub-freezing temps and snow for several months a year.
I know probably a dozen growers from all over Northern California who all manage to grow VFTs that get proper dormancy every year. You have seen my average temps, most of them are comperable within +/- 5* or so. As I stated earlier, it is normal for us to have daytime temperatures into the mid 70s right up through November around here.
If you want to see some hard numbers than have a peek at this. *Here are the average temperatures of both Palmdale, Ca and Wilmington, NC.

Based on this evidence I believe that Joossa's temperatures are well within the tolerance of the VFT. They are not even close to being too warm, let alone "Far too warm". I feel completely fine telling him "oh sure! no problem! its all perfectly nice and wonderfull!" because it is. Now if he were growing bonsai trees then maybe it would be too warm.. *good thing he's growing VFTs and not bonsai.
