Bill,
I started off using the TrackMaster (Equibase) Speed Ratings because they are fairly public and widely used and others who didn't use adjusted RDSS numbers could comment on them (e.g. Dave S). Also, they are on a reasonably similar scale to DRF, Beyer, HDW, etc and the guidelines about gaps between SR points might be applicable.
Moving along, I think I'll be using some (or all) of Adjusted Total Energy, Adjusted SR, or Perceptor Total instead - at least, comparing their results to what I've seen so far. I also believe the same measuring system can measure a component of Late energy to be mixed in somewhere and to be given extra application for those horses designated Late. I'm experimenting - my favourite thing!
As
Socantra pointed out elsewhere, and as those who are studying it so far will know, the interesting thing is that the Early and Late analyses come from a look at the horse's whole performance and not just one paceline. It is amusing (though understandable from a marketing point of view) that Dave proclaims that this involves '
no paceline selection', as if the relevant information were magically found in the Earnings box. In fact, if you look at the Hi and Lo Speed Ratings, and compare them for each horse to its Past Performance lines, you can see clearly which individual pacelines were selected automatically to derive the Hi and Lo SR numbers. That is one of the valuable improvements here: it's another
automated paceline selection approach based on some mathematics for measuring
ranges of values - and then some clever subsequent sorting and filtering by Early and Late running style groupings.
Just like ANY other automated line selection strategy - of which RDSS 2 has several. When you get a strategy you like (either a canned one, or a user-tweakable one - I'm trying for both), the pacelines and every analysis based on pacelines get selected automatically when the race comes up. For 1 race or for 200 races per day. New and improved: RDSS 2.0
featuring absolutely no paceline selection (except for the lines you tell it to select for you, or which you prudently override
). Maybe I need a better marketing manager!
I appreciate Dave laying out the mechanics and many examples of this approach for all to use manually - though manual calculation, just like manual data entry, gets old really fast. Software implementation is a natural next step, as HSH users know. And soon RDSS users.
No disrespect intended to Dave's proposition that it's not based on paceline selection (but it
is). And it's worth studying further.
