I agree with the formatting suggestions, but I also think that your schedules need to be as long as they need to be. I try to keep my schedules to one page, but sometimes that's not an option for whatever reason: too large a cast, too much material covered, etc.
Never heard them called weeklies before.
Maybe it's the format that needs to change, not the information you're including?
I've attached one of my 'weeklies' below, just a working copy and not the final distributed version, but not much is different. This was for 8 10-minute musicals featuring 10 actors, so a huge scheduling mess. I used to do this in Word, but recently started using Google Docs as well as emailing and printing, and Excel uploads much better, so I'm trying to make the switch.
