I guess I'm one of the lucky ones. I have developed 12 sheets at a time 
with no problem (2-2509N reels in a 2551 tank). I've also developed 6 
sheets in combination with 2 rolls of 35mm. (This was actually E-6, though, 
not b&w, so I don't know if that makes a difference. But when I've done 12 
sheets, it is generally b&w.)
