Yes that makes perfect sense. So the question remains, what is a
sustainable launch cadence from a single point of departure? Narrow
launch windows don't help if the hardware has reliability
problems. Which of course as you rightly point out in many cases are
necessary. Does that argue for multiple launch sites and more staggered
launch slots? Again we don't really know, we've never experienced this
level of traffic before. It will all be very interesting to see how this
unfolds.

Virginia has about 8 orbital launches per year, Canaveral about 35 to 40.

Maybe a few more could be moved to Virginia.
