I ended up tapping my two tubing runs Thursday night 2/9, a total of 45 taps on 5/16 gravity. I boiled 60 gallons Saturday, 70 gallons Monday, and 50 gallons Tuesday. So far i have bottled 3.25 gallons of Amber syrup (69-72% transmissivity). Only had a few hours of below freezing temps last night between 7pm-midnight, so not sure if i am going to get much sap to boil today. Its looking like things will be too warm until we get a solid freeze again Friday night and then hopefully Saturday, Sunday, Monday will be good flow days. Based on past experience I probably have about 1 gallon of syrup "trapped" in my continuous flow pans so that jives with the 180 gallons ive collected being at around that 40:1 2% sugar content. Ive never invested in a sap hydrometer, should probably do so one of these days.
