Good addition here, and it is hard to make a 'scientific' chart. I spent a few years attempting to compile one, and there's a few powder manufacturers who publish the specific's of their powders.
And some other manufacturers, to which when you ask them for the same type of specific data, they reply "offendedly" as if one asked for their personal banking information.
And yet, it is THAT information that adds to the specifics for all the players, right? I gave up, and donated all the info I had compiled.
For some, it is 'free' and others it is 'super-secret'. Interestingly confusing in this day and age of "buy our stuff because we're better'er and proud of it". :D
