Forecast Odds

[Snoopdog]

In an obvious forecast like the Goodwood 3.35 : Stradivarius 4/5 (clear and odds-on fav) beats Torcedor 100/30 (clear 2nd fav), the odds  basic rule of thumb (of add 1 to 2nd, multiply by winner) does not work well. Ie 4/5 x 3.33+1 = 3.464/1

I don't have to hand the w/o Stradivarius price of Torcedor, but I think: add 1 to the w/o price of the 2nd fav, then multipy by the fav price would be much closer.

The forecast paid £3.80 = 2.8/1

Does anyone have the w/o Strad price of Torcedor near the off, or other related ideas? There seems a lack of transparancy re forecast (CSF) odds.
