ROI Calculator

[Cliff]

All,

Was attempting to calculate ROI on top two ranked factors, specifically rPRB%. My ROI formula doesn't work except for one ranking at a time.....in other words rPRB%=1, or rPRB%=2.......can't seem to finnagle a way to get the math to work for r1 AND r2. Any suggestions, or, any one have one they'd be willing to share?

On a little different subject, I was doing this exercise on the recently ended Lone Star meet and found that there were 715 rPRB%=1, and only 711 rPRB%=2. How could that be? Didn't think ties were a factor with this ranking. Also looked like rPRB%=2 had a little higher (less loss) ROI than rPRB%=1. Has anyone found this to be the case at other tracks?

As always, thanks in advance for any help.
Cliff

under nPRB try
">=1 and <=2"

Cliff;

There are many factors where Rtg #2 will have a higher ROI than Rtg #1. The somewhat higher odds you get on #2 offsets the lower win %. I have a couple of spot plays using the M/L where I block the #1 ranked horse in a category or two.

Would add that "many" htr factors have a much better return on both rank 2 and 4 than on rank 1.
Rank 3 for some reason always seems to be "breakeven".

Should have said the above is true when filtering "down" to more detailed level. For example HTR consensus rank 4 normally will not show a profit as a standalone factor. "Drilldown" to HTR consenus rank 4 for dirt/claiming/routes/3up and most tracks will have decent return. Add in a decent LP rank and above is usually an above average spot play.

cliff......most htr factors do not have ties which is a feature I like very much. Not sure about PRB% but seems like I have seen some ties visually. Will check the db tonight and see what I get on it.

George, When you say "drilldown to etc" what do you mean?

Jack,
Sorry for using a data processing "buzzword" where plain english would have worked.
In a database query if you selected all 4th ranked K factors with no other filtering
it would usually show a negative return. If you then changed the query filter to
select all 4th ranked K factors at SAR on fast dirt claiming races for 3 year old and up
horses it may very well show that to be a winner.

You have filtered "down" to a more distinct level.
