Hey Kenchar,
Right well here goes, I presume it had more to do with the fact there was a large descrepency in the place odds between the bookie and the tab. You said before you look at the bookies odd to get a truer view of the horses real odds i think, SO when you saw the bookies have it at 1.90 but the tab had it at middle $6 then there was a fairly large anomally hence the nose twitching, do i take it kenchar you hold the bookies judgement in there markets in a higher regard and use it as a guide to find the descrepencies in comparason to the tab markets which all the sheep flock too.
I think i am just stating the obvious from what you have said previously, but do look forward to hearing the correct answer to your question.
