Making the assumption that the earlier runs were at Milan on 9-1-2019. The D/A yesterday from 10-4 ranged 254-1223. The previous date at the same times1284-1873. So some of your improvements were due to weather. A gain none the less. As far as fuel consumption. Last week a Mid Michigan we made 9 passes. Used just under 5 gallons. This weekend at Dragway 42 we were pitted at the end of the track. The runs were over a 2 day period. The run times were further apart. This entailed more warm up. 7 passes 5 gallons.
