'Calls' in horse race? As long as they are racing on a totting track or greyhound track [set-up for it], no problem. At a lot of tracks you are flat out getting an '800m' call. Where they were at the 'turn' is as good at it gets on most tracks except the major metro's and where they were at the turn is everything to do with class of race, jockey's ability and/or luck in a race, track layout, conditions, distance, running style, and barrier draw to suit it [or not].

More sobering is to have a look at the form lines of many winners for their last 4 runs. There is often a lot of 5,6,7,8,9,0 in them due to many, many variables as previously mentioned in some posts here, that often have nothing to do with ability. I'd be more wary of 2 straight wins [a big rating figure for most stat. methods] in the last 2 starts than 2 unplaced runs. Like glue-on shoes, very few horses win with either attached to their names at their next start :-))

I think if a lot of punters put a 1/10th of their energy into learning how to handicap as they put into gathering 'stats' and trying to come up with winning rating systems [often over a LOT of years], they would already be ahead of this game. Sure, messing with numbers will bag you some winners [so will my aunt Molly throwing darts], but common ****** sense and a bit of reasoning, will come up with a lot more.
