I agree it is always contentious as to what 48 hours means. To me it means 48 hours.
I would prefer that the committee move such that if for a motion to be debated on, say, a Thursday, it would need to be submitted prior to committee on Tuesday. That way there is a full 48 hours' notice.
Otherwise, what often happens is a motion is moved late on a Tuesday afternoon or evening and then it is brought up for debate on Thursday, which is not even close to 48 hours' notice. Often the other parties don't learn about the motion until the day before the committee meeting.
I would prefer that we stick to 48 hours' notice. We all understand what that means. It's 48 hours.
