[foxboro] Control Loops.

Hello,

I am trying to find out if there is any standard as to how many control
loops a console operator can reasonably handle. I recall an old rule of
thumb that defined "equivalent control loops": 1 valve or 4 indications =
or 8
contacts can be considered an "equivalent control loop" and an operator =
was
supposed to be able to handle up to 250 of these. Any insight on the =
matter
will be very wellcomed.
Thank you.
