Q: Is there a timetable for the release of the new RDSS version?

A: I plan to make a fairly detailed post either later this week or early next week (e.g. March 11 - 16 period) outlining my best estimates for initial Beta release, then for the final release of RDSS 2.1 to the existing Subscribers. Also a Summary of major new features, plus the 'roadmap' (as I see it) for the rest of 2016 and subsequent releases. Also, very important, soliciting your feedback! This Summary will be followed by some initial walk-through videos, more screenshots and live handicapping using the tools, prior to a scheduled limited circulation Beta, then Final release.

Thanks everyone for your patience over almost 3 years now while I have worked out a fairly major new footing for RDSS and tried to find a way that the project continues to be exciting and enjoyable both for me (it's both my *livelihood* and my passion) and for all of you (and perhaps a few new people as well).

Update: Here is the new Forum for RDSS Version 2.1: http://paceandcap.com/forums/forumdisplay.php?f=149

Hey there, I searched the forum and looked in this thread, but I can't seem to find a basic description of the DTV. I know it is Daily Track Variant, but not sure what the numbers mean.

Does a negative number mean it was a very fast track?
Does a lower number in DTV mean the track was faster than when there is a larger number?
What is a "normal" track DTV? How do I find out what is the average number for my track?

Using Synthesis Manual Entry, I know 16-18 was a normal track using the DRF's variant. This was pretty simple to understand. Going down, every 2 points lower the DTV was, the race was adjusted 1 "length/tick" approximately as faster. Once again, this was very easy to understand and visualize. I am still trying to understand the RDSS 2, which I love btw, but I need to understand it better to really understand what the horses did on what kind of track. Any help on the DTV is appreciated, Thanks, Dan

Does a lower number in DTV mean the track was faster than when there is a larger number? yes
What is a "normal" track DTV? How do I find out what is the average number for my track? 0 means track normal



I’m not a rdss user, but they come up in Val or Spec.
I think they are the same as the in pdf trackmaster file . Say –3 fast= 3 tenths or 1.5 lengths fast.
For example 0 even track.,10 .slow 5 lengths, now say –7 fast 3.5 lengths or 7 tenths fast. This is how I have used them
I have reverse engineered these variants , and think they are pretty good, mind you this is a final time variant, made from par times.
Dan, I do not know what all goes into the making of these numbers, but they much better than the DRF's variant
I’d just be wary of using lines that are to extreme. Say like +19 on a off track

Thanks Peteman, I am used to the DRF variants so the TM ones were kind of throwing me for a loop. Appreciate the help, Dan

Trackmaster DTV

Trackmaster uses the following formula for determining the effect of the DTV

Time Adjustment = .0125 * d * DTV where d is the number of furlongs in the paceline race.

So a -10 DTV in a 6 furlong race = .0125 * 6 *-10 = -.75. In other words according to Trackmaster this race race .75 seconds faster than the Par for this race class.

Hi Mark,
That would tighten up the numbers some.A single variant point at each distance,a minus 10 points at 6 =.75 secs fast.or say a +20 at 7 fur
would be 1.75 seconds slow final variant.Thanks for the input.This kinda makes me accept a +20 var number a little better.

Code:
	Value			
Fur	single			
Dis	Var point	  -10 var		+20 Var
5.0	0.063	   0.625		   1.250
5.5	0.069	   0.688		   1.375
6.0	0.075	   0.750		   1.500
6.5	0.081	   0.813		   1.625
7.0	0.088	   0.875		   1.750
7.5	0.094	   0.938		   1.875
8.0	0.100	   1.000		   2.000
140	0.102	   1.023		   2.045
170	0.104	   1.040		   2.080
8.5	0.106	   1.063		   2.125
9.0	0.113	   1.125		   2.250

Sorry word wrap makes this hard to read. key

col 1 dis 5 fur
col 2 a single variant point a 5 fur .063
col 3 what a minus 10 at 5 fur looks like .625
col 4 what a + 20 would look like in seconds 1.250

Peterman,

It makes a great deal of sense. But from being right on to way off, you never know. So I don't use them. I do use ITV however.

In my view final time is completely reliant on early pace. I don't know the percentage but I believe it is a good 50%. You don't get fast final times without fast early fractions. If you have a bunch of SPs and S in a race or slow Pressers, nobody wants the lead. You see it in turf routes all the time. You see Pressers who can finish against a 1:11 but some slow E or EP grabs the lead and they play follow the leader through 1:12. There is a limit to how fast a horse can run the final fraction, they are flesh and blood.

So it makes absolute no sense to me to make final time variants that don't in some fashion take into account the early pace and it makes less sense to apply a final time variant to early fractions. It's nonsense. I don't know why some really smart guy hasn't figured a way to do this. Hell, it has been done this way since early TPR days. Pizzolla showed how he adjusted DRF speed ratings by 2nd calls off his fulcrum pace. If I was 20 years younger I might make a stab at it, but I have gotten to lazy and so I just don't use them.

Mark, when your doing your match up your kind of free from this ball parking of numbers, and are able to concentrate on the flow of the race.
I can’t match, but we can look to for who will be advantaged by the pace, I see there is freedom from the exact value in numbers.

Imo the final time varient does not reflect the fractional splits 50% of the time as well,I used to make pace and final time variants
Too much work, fortunately for us the first 2 fractions are not stepped on too much .by most of these programs we use.


I too wish I could up with something new,a pbs or a ppf spinoff,I think we need things that are unique,or something old we can master
I’ve tried race shapes, pace pressure gauges, running styles, pace of race to get a clue of the race the horse is coming from.
Now I’m comfortable with velocity ,as old as it and I am.

Thanks Bill, for cleaning up that number mess.
