I haven't kept track, but supplementing my 2-roll tank with a 5-roll tank helps 😉. I used to do a lot more intensive recording of information, but I scan everything now, so everything is organized at that level now.
I am amazed sometimes when I look over the four binders full of negatives pages I have. More that I've taken a lot of pics, and that I should be better than I am.
My CL definately has pumped up my average for the last year.
