Edit : Re your question i have just noticed that you specify the lto run, but my above is past ratings in general. When looking at a lto run which appears poor the first question i would ask is was the animal placed to win or was it a gaming run. If i conclude the latter then a poor run would be a positive from the stables perspective.
I like to pay more attention to a horses 3rd last run rather than its LTO. If that race is of the same type as todays race and the LTO, 2LTO were distance or class moves it can add points to SP if not noticed by the betting market. As you indicated mick, last couple of races could be 'throw-off the scent' races.
HRB have recently started including this information in results. Before this I used Timeform website for it, you have to register to access this information but it is free.
Same here. I always look to see if its worth attempting to pinch an extra point or two in-running, over and above the possible BFSP, especially around the favourite if its tight at this end of the market.
Best assessed near the 'off', to guard against any daily odds swings, if you have been too late to get an early price about a horse.
An example for today (have to go out so done it now).
