Since I don't have a GCR handy, I'll just take a crack at it...

"No".

And the "No" would still be a "No" if you "retired to the paddock" in an enduro which allowed "retirement to the paddock and then return to the track". BFA = Black Flag ALL.

The same would be true under "Red Flag" conditions, too (just to throw an additional complication in there).

(JW...an SIT...who will probably STILL be an SIT when Raymond get his Nat'l Chief Stewards license)
