Some solutions really are remarkably long-lived, aren't they? I never did much RA4, but my experiences with the Ilfochrome P-5 process were that the dev lasted for aeons, whereas the bleach-fix was exhausted if you just turned your back for a moment. I packed it in in the end - just too much of a problem having to work like a dog while the solution was fresh and then wait until I could justify a new batch, etc.

Never was as much fun as B&W printing anyway. :-)
