The OP from the other forum says the charge by weight for R152A is 20~22 oz, based on molecular weight. Since it sucks to wade thru 40-ish posts to find relevant info, I packaged the OP's instructions into a single handy PDF file - see attached.

There may be another reason why I couldn't get that full 2nd can in.... In order to retain my AC & PS with the FFE crank trigger kit, Angry Stig came up with a brilliant solution using a backwards mounted spare FC Alt/WP/air pump drive pulley & some AL spacers. Since those pulleys are smaller in diameter than the stock AC drive pulley, I'm now under driving my AC a wee bit. So it is very possible that when I was charging the system at 2000~2500 RPMs per the instructions, maybe I should have been revving it higher to draw that last can in?
