I guess 3 days is not enough, especially in this time of year.  My
rule of thumb is to wait at least a week, possibly two.

But in any case, the amount of time you waited is not the main issue
here.  The main issue is that we decided to implement this the way we
did, and you were even part of that discussion.  It makes no sense to
undo all that because you suddenly don't like the results.
