The Bottom Line Betting Line....

[atlasaxis]

Is this software still available/in use? Thank you.

Bottom line betting lime is not a program itself
It is the final rank or sort on all the later Sartin Methodology programs.

Hey Tom,

As Bill says, Bottom Line/Betting Line (aka BL/BL) is the core betting line in all Sartin software for the past 15 years. Many of the RDSS screenshots show precisely that, and it featured centrally in Speculator, Validator, Synthesis, PaceLauncher and older I think.

Along with VDC (Velocity relative to Deceleration) it's probably what we use the most (though not exclusively), from a pace/energy distribution point of view.

cheers,

Ted

P.S. I'd welcome you to Pace and Cap, though I know you've been around here for a long time Anyway, good to hear from you!

Hi Ted,

Thank you to you and Bill for your replies. My asking about this arose from reading this article http://www.sartinmethodology.com/lib...L_Research.pdf

and was wondering what software Cramer might be referring to if the BL/BL is not an actual program. In the programs that you mentioned Ted, can the betting line be changed when scratches occur? Thanks very much and thanks for the welcome to the board.

Best regards,

Tom

Tom,

The Sysnthesis software was current when Mark Cramer and Doc (and Aline Best) did that work (1997?) BL/BL was/is one of several screens from that (and subsequent) software. You pick a past line to represent a horse in today's race, you rank various factors in all the resulting lines, then sum the ranks with certain weightings for ranks, and differentials between ranks and values of the underlying factors themselves. Which results in a weighted line score (the 'Bottom Line' was Doc's moniker for it), which gets expressed as an Odds Line (the 'Betting Line') = Bottom Line/Betting line.

If a horse scratches from the race, you remove that horse from the mix and the Line is re-ranked, re-weighted. Same if you remove a horse from contention.

For example, here is the Bottom Line/Betting Line screen from RDSS for tomorrow's Whitney at Saratoga:



The Bottom Line shows Quality Road a slight leader over Haynsfield, while the VDC shows them equal. The equivalent Odds Line (the Betting Line component) shows them equal at 8/5. QR will be closer to 8/5 than will Haynsfield.

In this particular race, I have a hard time accepting that Mine That Bird is a real runner here. If I should then 'scratch' him, Blame and Musket Man achieve co-equal 3rd ranking.



Other considerations aside, the value oriented wager would be a split bet on Haynsfield and either Musket Man or Blame. On the numbers, QR is on top due to only his last line. Either he has found a new gear, above the rest, with that last, or his best Total Energy from all his other efforts is not at all so superior to Haynsfield, and not an overlay at 2/5 ML.

On a long term basis, QR is not a win bet here. That is independent of whether he might actually win this particular race, and certainly whether he belongs in an exacta.

Just some thoughts on BL/BL

cheers,

Ted

Hi Tom

Here is theto w BLBL from Val 4 which is very similar to what Mark Cramer was using in the article The 3 horse is rated fist (its the top rating)
under the 3 is the 4 than the 2 than the 5 and 1
The 5 was 3/2 at post time Any horse I wanted to "hide" or scratch from view can be done from this screen
The beauty of this is when a horse is scratched or Hid you get a new sort
beauty of chaos often gets you longshots moving right to the top 3 BLBL

[Bill V.]

oops Looks like Ted and I both were posting together
In this race the 5 won but rated 4th I
bet againts it I the bet the
3 and 2 place and show
the 2 placed They DQed the 5 and there you go a 14/1 placed

[Ted Craven]

Since this particular Forum is about older Sartin software, here is the BL/BL screen from Val4 for the same race, same lines (bit different picture, but possibly the same bets):



In some ways, Validator's alternate approach to the calculations adds confidence to my feeling about skipping over QR in the Win Pool.

Bill, yes indeed - many ways to cash a bet, congrats. Some good different examples of BL/BL throughout the ages.
