Before I start, I am actually a "madam"... *shocking* LOL It's all good. These were all at six furlongs at those specific tracks with a mishmash of all classes, sexes, age, etc... I was experimenting with a side project of what the general average is for each winner and pinpointing patterns/idiosyncrasies with a specific track's distance, surface etc... versus others. As far as incremental and track times, I dohave that available so I will check that out.

OK, here's some food for thought. What does %E mean? %E tells you the percentage of a horse’s total energy it uses to the second call. In some circles this is called "median energy" and is expressed with number in the mid to high 60's or low 70's. For purposes of this discussion, I will use track “A” and track “B”. Both tracks are one mile ovals. Both tracks have a conventional dirt surface. Track “A” has a run up distance of 35 feet. Track “B” has a run up distance of 60 feet. Track “A” has an average %E of 51.00 Track “B” has an average %E of 53.00 You know the average %E is accurate because you calculated it from every winner, for every race, on the dirt, at each track, during their last “entire” meet. Does track “A” have a lower average %E because the run up distance is shorter? Does track “B” have a higher %E because the run up distance is longer? Does track “A” have a lower average %E because the winners ran more sustained? Does track “B” have a higher %E because the winners ran more early?

FTL,
I'm comfortable with the notion that the Match-Up itself may well overtake the prevailing track conditions. I think what has set me thinking really is the "middle ground" so-to-speak, where the prevailing conditions are having an effect either positive or negative in addition to the race Match-Up if this makes sense. Can't remember which tape I heard it on, but I think the quote was 55% of races being decided on the race Match-Up. In the case of the Track A & Track B comparison I'd have to say first off that I perhaps don't have enough experience with looking at different tracks to be able to infer anything from the above figures. These figures may well be conveying something strongly, but I don't know. That said, my thoughts would be that when looking at this as bare information is that perhaps the data we have here in isolation is incomplete enough to form any meaningful observations. Track A has a shorter run-up and a lower %E, which could be in part down to the lower initial fps that the horses were travelling as they tripped the timer, but may also be in part due the track configuration. The opposite is in effect at Track B, longer run-up & faster fps at the timer & again, no idea of the prevailing track conditions. Essentially, I'd have to say that I don't know the answer to this. Thanks. |

FTL,
Would you please be able to clarify how I treat sub-6F distances when calculating the %E. In MPH Tom B only goes down as far as 6F, but I'd still like to be able to do everything accurately even if it is less applicable to the shorter distances. |

I will use the same half mile time in each case. To make it as easy as possible, there will be no beaten lengths. If there were beaten lengths, then they would have to be included. First, 5 furlongs. A half mile time of 46.0 seconds = 57.39 feet per second (2640=feet in a half mile/46.0 seconds = 57.39 feet per second) If the race is 5 furlongs, that means there is an additional one eight of a mile or 660 feet. If the final time is 1:00.0 (60 seconds), then the last fraction is 14 seconds. You take the 660 feet and divide by 14, which equals 47.14 feet per second. You then add 57.39+47.14 = 104.53 Then take 57.39 and divided by 104.53 = 54.90 %E Next, 5.5 furlongs. A half mile time of 46.0 seconds = 57.39 feet per second (2640=feet in a half mile/46.0 seconds = 57.39 feet per second) If the race is 5.5 furlongs, that means there is an additional three sixteenths of a mile or 990 feet. If the final time is 1:06.2 (66.2 seconds), then the last fraction is 20.2 seconds. You take the 990 feet and divide by 20.2, which equals 49.01 feet per second. You then add 57.39+49.01 = 106.40 Then take 57.39 and divided by 106.40 = 53.94 %E

Med Energy
Thanks FTL
Dave or anybody who uses RDSS2 Its very easy to figure the Percentage Early Go to the E/L TPR tab and divide the EPR by the CPR (tpr) Here is the last pace line for horse # 6 The percent Early is 52.05 EPR 89.9 / Total 172.7 = 52.05 %E Of course RDSS has the similar Med Energy which tends to be easier to model The number's tend to be in closer ranges of acceptable parameters |

Example
Here is a column from my Parx 1 mile none maiden model
These are all from winning horses from the result charts I have split the column, The Med Energy numbers are in a small area mostly in the 68.00 - 69.00 range. Under that are next few none maiden 1 mile distance winners in Percentage Early numbers Notice the wider range of about 44 to over 50 |

FTL & Bill,
Thank you both ever so much for your help with this area. I feel ready to go with this now as an additional factor. It should be easy enough to set up spreadsheets to address the calculations to work with the RDSS extracts and also analyse how a track is running on the night. I might as well do it for the %E & %Median & so I'll have both figures to hand. I'm aware that there was a move towards %Med, but I find %E easier to visualise. I guess I'll see how things pan out over time. Thanks again both. |
