Through the chair, I'll respond.
Some of the committees I've worked with have waived the notice or changed the notice to 24 hours. We find that 48 hours' notice actually is a real barrier to those working on the committee. It often spans a weekend, and it makes it very difficult to keep the committee moving promptly when you're bound by that 48-hour rule. It actually expedites the work of the committee to have only 24 hours. Anything shorter than that I would be reluctant to recommend, because the clerk and the staff need time to incorporate those motions--at least overnight. “One sleep” is what we go by.
