I used the Grand circuit just as a pointer as to why I can't decide on a favourite distance. Every class, track etc is different. That part of my post was just thinking aloud rather than replying to you!
When, as a driver (and to be perfectly honest you don't need to be a driver, random drunk can see it), you are on a horse who is outclassed and it just doesn't matter what you do you can't win...is that not a part of racing? Plenty of times in footy I've been in situations where in a one on one contest or as a team we've been outclassed. Thats sport. There are things in place in harness racing to help stop this from happening eg claimer races and drop back a class.
How exactly does one program races so every horse is around the same mark. Not only that but then so after the barrier draw things are still pretty even. My answer would be the current system work pretty darned well (not perfect but who and what is). What is yours? I'm guessing stand start handicap races will be your answer. Please summarise specifics of your plan in your next post. :)
I find your stand start races claim hard to believe. Stand start races are generally trotters races and they have a knack of finding themselves as either the first or last race on the card - especially so the last race. For turnover (and on cold nights), pacing and trotting alike, the last race isn't the place to be. As for pacing SS races well there just wouldn't be enough data to make a decision either way. But if you say its fact I will indeed do my homework, all my teachers who sprouted facts had textbooks or something to back it up, do you have something I could look at?
As for predictibility. I believed you were saying its predictable because of the current handicapping/fields conditions. If I've misinterpeted I do apologise. But how does one handicapping system bring in unpredictibility?
