Nope!  Because of the way Remind's algorithm works, that is not the
case.  For BEFORE, the OMITted days will be in place correctly,
but not with after.  Run in debug mode to see what's going on, and
maybe watch the part of the intro video where the algorithm is
explained.

I can't figure out how to do it.  As I wrote, making reminders depend
on other reminders is tricky and it looks like your use case isn't possible,
unless someone else can come up with a solution?  The issue is that
in your case, the date of a reminder potentially depends on *all* possible
past trigger dates of the reminder, and Remind just doesn't handle that.
For example, to know when to trigger "Gym", we need to know the entire
history of the Practicing, Library and Gym reminders because a shift even
far back in history can change today's reminder.
