Side by side testing of the Derby Magic track and a BestTrack®

In April, 2011 we purchased a 3-lane, 35 foot BestTrackt® to compare to our track.  We tested it
against our 3 lane, 32 foot Derby Magic track. We wanted to compare how consistent the two
tracks were.  We used 3 Pinewood Derby® cars that a local dad had made over the years with
his sons.  The cars were selected at random and were each weighted to 5.0 ounces.
We used a Derby Magic timer and the Derby Magic race manager software on each track.

The test format was as follows:
Each car raced 3 heats on the Derby Magic track, one in each lane.
Each car raced 3 heats on the BestTrack® track, one in each lane.
Each car raced 3 heats on the Derby Magic track, one in each lane.
Each car raced 3 heats on the BestTrack® track, one in each lane.
Each car raced 3 heats on the Derby Magic track, one in each lane.
Each car raced 3 heats on the BestTrack® track, one in each lane.

We set the testing up in this manner to minimize the impact of the cars degrading over several
races so we would get a fair indication of what each track was doing.

A detailed listing of the results are below, but in-short, the race times on the Derby
Magic track have less than half of the variability of the BestTrack® track.

The Derby Magic track is faster than the BestTrack® track.

One of the test cars would not make it all the way down the track on the BestTrack®
track in any heat.
 The car stopped 3 to 5 feet short of the finish line in every race.  Imagine how
disappointed that child would be.

This was a data driven test, and the Derby Magic track is the better track.

The racing surface length of the two tracks are:
Derby Magic track              30.0 feet
BestTrack® track                31.5 feet
The racing surface of the BestTrack® is 5% longer than the Derby Magic track, but the times are
more than 11% longer on the BestTrack®.  The longer surface on the BestTrack® does not
make up for the longer race times.

Spending more money for a BestTrack® or other aluminum track will not buy a better track, it will
just cost more.
