This SC restart thing will be fun to go over.  After sleep of course 
 
I'll/We'll also take this investigation as a chance to review/revise/clarify SC procedures throughout NDR.  
The SC speed is always a comprimise between keeping the flow going, keeping tyres warm, and letting people catch up.  I reckoned that the 150 kph speed would have been sufficient.  But it ended up not being.  I did go slower than 150 kph on a few occasions to try and let everyone catch up.  
I accidentally Shift+Xed when I intended to Shift+Z to hide the mouse cursor, which I had up after qualifying.  Sorry for that press. 
 
Anyway, we'll figure it all out as soon as we can.  

  Thanks to all for racing, it was great to see a 20 car grid starting.
