Seems about right.
I would guess 2-3% from the preheat (2kWh avg 8kW for 15 minutes)...I guess you did not make note of % prior to turning on?
I’ll never see the snowflake so I will never know how it works. Do they show green plus some blue? Where green is miles available and blue is the portion you will recover? But they don’t tell you the exact amount of miles restricted, you have to eyeball it?
It shows a blue hatched portion. From what I've been able to tell, it has about two "thicknesses" (determined by taking numerous photos during a drive in which it took ~45 minutes for the snowflake to disappear). If it is pretty thin (about 3-4 hatch patterns thick IIRC), it will disappear quite shortly. The thicker version is more like 6 hatch patterns and persists for quite some time before getting thinner, than disappearing all of a sudden. What happens while the snowflake is on is that you consume "rated range" on the display slower than usual. Your efficiency and energy consumed values in the trip meter will be correct. (Incidentally, starting a drive with a snowflake causes TeslaFi to drastically underestimate the amount of energy used, since it seems to just subtract rated range consumed... it doesn't read the trip meters in the car directly.)
So TLDR;, the rated range you are shown with the snowflake is the amount of rated range you will be able to use if the battery doesn't warm up. (As it warms up, you magically consume rated range at a slower rate than usual.)
