I would imagine the 21 would suit its normal times but something like the 28, not sure it would, I'm taking guesses as I'm not from the area.
Going by what I've seen on Sundays, I think the 21 needs upgrading to every 7 Mins like what's shown on Monday - Saturday, Also on Monday to Saturday the service needs upgrading to every 4-5 Mins -
Newcastle City Centre - Chester-Le-Street.
