I put in a lot of time in high school. I used to stay until 2am some weeknights. There were some overnights when preparing for pre-ship events. I was also taking a full load of AP classes, working and playing varsity basketball. So I had a lot to do but somehow (lots of Mountain Dew) I got it all done successfully.
Honestly, I think I wouldn't have learned as much if someone had capped my hours. I certainly wouldn't know about time or project management.

The team I graduated from no longer has as insane hours. Now meetings end before 11pm. The team has grown so the work is more spread out. Overall, they meet for fewer hours but are still a successful team, in fact they could be considered even more successful now.
This was done by doing work outside of meetings and making the team more efficient. There are lots of emails and other communication messages so that everyone knows what needs to get done before the meeting starts. CAD has also become very important and helps save design time.

With every team I work with, Fridays and Sundays are off unless something horrible has happened then we might meet for a few hours on Friday.

I think it would be difficult to meet with those times because of them availability of mentors. It might also be hard if the students need to work on things after school. My teams meet from about 5-9 but students can come early to work on homework, eat, CAD, etc.

I'm surprised to say that based on the average number of hours we would be able to function with those limits. However, I know that without the people who went over the average then the team wouldn't be as successful.
21 students worked an average of 15 hours during the pre-season. 9 mentors worked an average of 28 hours. There were 12 pre-season meetings. This time includes work done outside of meetings for students but not for mentors. The reason the mentors have a higher average is because some of the students only came to a meeting or two.
17 students worked an average of 85 hours during the build season. 15 mentors worked an average of 72 hours during the build season. The students worked an average of 40 hours after the robot shipped. The mentors worked an average of 29 hours after the robot shipped. This time includes work done outside of meetings for students but not for mentors.
I think I need to re-run these numbers because they seem low.
