I believe that the proposed rule to have a 30 day period for response to requests for supervision is very important to the supervisee in terms of their ability to plan their schedules and work venues for supervision.
Further more, I believe that given the backlog that currently exists, backdating approvals is only fair to the people who have been waiiting months to know if the work they may be doing will be approved.
It is very hard for students to find opportunities to do their residency and to expect them to wait for months to have that supervision approved is unresonable. Frequently students have less than a month between being accepted to do their work and the actual starting date.
