That is a very interesting thought - thanks! The track was definitely much colder at that point in the evening and I'm sure they didn't do a very good job conditioning it this year. In fact, last week was the first night they opened up the entire 1/4 mile (three previous weeks were 1/8 only).
It may be a little tricky to try to replicate on the street around here but maybe I could trailer it out to somewhere quiet.
