Thank you, Ed. It'll be quite difficult to fraction and store before usage, methinks. Will see.
As for volume/packaging, who knows? As a matter of fact, in my experience I can't recall ever purchasing two P30 or P30P kits which looked the same, had the same content and made the same quantity. Each time I went to the store, something had changed. Say: funny the developer comes in three compounds now. It was only two last time. Really, who knows.
