What has changed so dramatically in the last few years that would affect a decent system tested over 12 years ?? I have observed that there are certainly cycles in this caper, but there's cycles in everything.

I suppose training methods have changed where a horse can be set first up over a bit of distance. Weights have become compressed. But horses still have 4 legs and the fav still wins 30% of the time and LSW still win at the same rates they used to.
