I tested my new dragy tonight and here are a couple of runs. There were more cars in the area than I'd like so I gave up before setting any records
The VALID run shows a big difference vs. 1 ft roll-out. Is this because the car moved slightly before releasing the brake?
The INVALID run apparently was due to a negative slope, which I believe was mostly towards the end of the run based on the height line on the chart (correct me if I'm wrong!) Can I assume that the 0-10mph time from the INVALID run is realistic under my conditions?
If so there's potential for 0.25sec improvement over my VALID run. Is this how it works?
