The Speed rating using time is insignificant as it obtains more faults. Because the times are different may be a result of the track that day or the variant and or may have been accomplished on a different and slower track for that workout. None of these conditions, variant or track are considered, in a Speed Rating based on time. Better than nothing but fraught with faults.

The % of horses beaten is better tool because it eliminates those two problems, as it takes place on the same track under same conditions of variant, at similar period of time that day etc.

Now a horse can get as Ted states a same rating of 91 in his example of (1/11 & 6/65).
Are they equal? Absolutely not because the 6/65 workout horse competed against 65 horses, therefore the degree of difficulty is much greater to accomplish a 91 than against only 11 horses. It's an unknown what the 1/11 horse could have accomplished up against 65 horses. May have finished 11 or whatever. WE can't determine that, a complete unknown however there's no doubt it's a much harder task or degree of difficulty.

One way to solve this problem is analysis and putting these % rating into content. Is this horse entered today at the proper class, distance and surface. Yes, some work but easily accomplished by perusing the PP;'s If either are entered wrong their 91 rating is meaningless. Note: there are exceptions to this that I can think of, but they are an exception not the norm.

I'm sure there's a formula that can compensate for those differences however it's too much for my little brain. The 6/65 should get additional points for degree of difficulty but how many? Anyone have an answer? without a definitive scientific answer its better left alone or as is.
