My vote is "other" -
10 hrs accumulated total - allocated any way you'd like.

For example,
1 team might choose to use all 10 at one time, and be done with it,
while some may choose to allocate equal portions over X days,
and others may choose to split it up in unequal time allotments

So, depending on each teams dynamics (size of team, available equipment, and workspace, time availability of mentors and students) it would best allow all teams the capability of using the fix-it window as they wish to.
