Like it or not, but you just confirmed my "time is money" theory. Even if it would have been possible to create a process that needed 10 minutes at 20C, nobody would have wanted it back then.

PS: I fully acknowledge that Kodak would not compromise on quality in order to reach that speed goal. After all they still use separate bleach and fix.
