Hi jeebs, Great observation. Please don't get me riled up about the Trackmaster DTV and Intertrack adjustments. They are not the same as the DRF ones
They are all we have so we just have to accept them if we use RDSS
Yes If the DTV is a minus the numbers should be slowed down
The track is listed as "good" Maybe Trackmaster besides a final time par
and a track to track adjustment table , maybe they also make adjustments for the track condition . I think they also have some kind of race par mixed in But I may be mistaken
Anyway lets look at another example and maybe we can see what is up
Lets look at line 1 for this horse
RDSS gives it just slightly higher readouts than I did using a calculator
but RDSS/Trackmaster is much more accurate since they are using 10ths
I used fifths so I had to round up and down
Here is my work up for line 1
46.6 or 46.3 in 5ths =
87
113.2 or 113.1 in 5ths - 46.3 = 26.3 3rd fraction = 77 + 1 beaten length (rounded up) =
76 LPR
So For Whateveryouwant since it ran on a slow
19 DTV the numbers are adjusted up
Raw Adjusted
EPR 87 goes to 94.5 Because 65% of 19 =12.35 but we are using 1/2 of the DTV and Track to track so 12.35/2 = 6.175
LPR 76 goes to 80.2 We only use 35% of 19 = 6.65 /2 = 3.32
87 + 6.175 = 93.2
76 + 3.32 = 79 .3
The numbers are slightly off but relatively the same
The difference on RDSS is +14.5 Early and with my calculations 13.9 Early
