Thanks Merriguy. That detail is still only for the place-getters though, unless I'm missing something. What I meant was, on the WA Tab site, before the off, you can view ALL the current quinella odds - and I use this. This information (not surprisingly) is not available from history. So I can't retrospectively test my system which compares all pairs of win odds against their respective quinella odds.

The only retrospective testing that seems available is simply with the ultimate 1, 2 place-getters and the winning quinella odds.
As a variation I am looking at the equation from Wunfluova for value check.
