Bill,
Here's the Result Chart for B#'s last race (just click on the last race if you have the Chart data plan):
The 1st DRF column you see is the Post Position, not the Break (doesn't seem to be shown). B# was PP 4, but 1st at the Break or Start (Chart column above shown as St). TrackMaster PP data doesn't supply the 1st call running position for routes (the 2f point) while DRF does. The RDSS 1st Call point is the 4f point in a route, shown as Call2 in the Chart above, 2nd, beaten .1 lengths (shown as hd in RDSS), etc. I wish we got the 2f Position and BL in routes - it's a bit confusing.
Also, re Call times, DRF shows in 5ths rounded down, while TrackMaster provides the values in 10ths which RDSS shows as is. Thus, KEE #9 April 5, Chart final time shows as 1:43.69, RDSS shows as 1:43.7 and DRF shows as 1:43.3 (fifths) or 1:43.6 (tenths). I think RDSS shows more accurate running times.
Love that name: B# Sonata, much nicer than C Major!
