When I order five pound bags of various blends, it's hodgepodge on how much cubic volume the blends will have verses the weight, even in the same cut. For example, I can get 36 half pint jars out of Virginia #1, yet five pounds of McClelland 2015 only gave me 20 jars, both broken flake. I'm pretty sure this is because of water content and how easy it is to compress into the jar.
Full Flakes are about the most consistent in volume, but I pack them by weight, to keep from having to open up 8oz of a flake when the time comes and having the age and taste diminish before I can finish smoking the jar.
Sorry, to take you off-topic, but I thought that I was responding to your OP. I've noticed in the pipe hobby that if something is said a certain number of times in posts, it becomes a fact, no matter what the facts are. :wink:
