Hi Bloods, good job with that patch. You totally are doing some things right.
My rule of thumb is a hard frost. I have harvested at night during the first really hard frost, after watching the temps drop that day. Below zero is the temp I go by, but it really depends if its that cold all day or just for a short while at night. Obviously the short snap baby freeze being the "safe" option. It'll turn the hairs all darker immediately, usually, which diminishes the aesthetic appeal.
