There is a use for tiles that unveil themselves after the cut-off date that have long, worked out rationale behind what is expected in terms of calculations and why the grading works like it does for a lab report. This would mitigate some very lengthy support issues where we have to write page-long emails to a student or faculty member when they assume that our stuff is wrong (and it isn't).
Also could be very good to have these always available to the instructors/TAs.
