Rosin and puck THC Content
I found three studies that should shed some light.
High Times - They looked at all the THC tests of 3 years of Cannabis Cup rosin entries in 2014, 15, 16. They came up with a an average of 76% total THC in the rosin.
Extractioneering tested 60 samples of rosin, average was 73% total THC.
John B did three tests of used rosin pucks and came up with 13% total THC.
So using 75% as the THC content of the rosin you can calculate what the puck has using the weights of the rosin and the puck, assuming you have a general idea of the THC content of your original flower. I've read multiple places that short of having test results, using 15% THC for flower is a good start.
