I'm not sure what state you performed this in, however it is very well known that ASL interpreters can not interpret for hours on end. ASL interpreters are actually paired at engagements and must swap at very short intervals (20 minutes if I recall). Thus any figures you cited must be doubled.

You are correct, for the most part! We'd always use team interpreting at things like conferences with non-stop speakers and very few breaks. As someone who actually did educational interpreting, there is a lot of downtime/student work time. So, one interpreter is usually appropriate in a setting like a bootcamp.
