It's not an unreasonable question to ask.  It's a little harder to
actually get the data since we change our schedule pages.  I think John
Poelstra had tried to do some data mining leading to the proposal at
hand, but I'm not finding where he had stuck that off-hand.  I can try
to dig through some mail archives if I'm mistaken

My off-the-cuff response is that recent slippage has been on the order
of two to three weeks, outliers of 4-5 but most of those have had
extenuating circumstances.

If we do two to three weeks for F11 from May 28th, then we get the
middle of June.  If we add that to the shortened F12 schedule (since
shortening it more seems unreasonable, at least to me), it is scheduled
for mid November.  And any slippage putting us into the
Thanksgiving/Christmas quagmire.
