(Now you are sounding like one John P.)
On the surface, yes, there could have been 353 cancellations gross, but not net. Some of those cancellations could have become Model X Sigs, and some Model S Production.
Notwithstanding the cancellations, having the Sigs fully subscribed shows the robust demand that there is for the Model S.
It actually may be more, because we have to include around 200 SSLs. However, the US got some of the Sigs slotted for Canada (maybe about 50), so maybe plus net 150 for a total of around 500 original Sigs that bowed out for one reason or another.
