That "few tenths of a second..." reminded me of last night's conversation
with my son, Alan. Seems he participated yesterday in an autocross at Road
Atlanta. Won best time of the day and best average time. Then he told me
that the last run, his best, was made with only 3 cylinders firing in his
Ford Focus, due to a blown head gasket. Made me comment "Maybe it's a clue
that you need to slow down a little...". "I think maybe you're right."
It ain't always "the faster the better".
