Ah the numbers of which the mighty Parker speaks. I got 12.1 gal per tap on buckets in 2009 so 13 gal per tap is certainly obtainable. I only got 7.7 this year from the same trees but this was a bad year for buckets.

Last year from the tubing with suck on it I got 19.2 gal per tap and this season only 17.3 gal per tap. The sap goddess and the weather gods were in control. I was without power from around 11pm Thursday night until 11:30am Sunday morning the weekend of the wind storm. I could have made my averages if I had power those three days.
