Yes, makes sense , in fact I did a lot of research on PP favs. watching until exactly 1 minute b4 the off and backing only if the nag was (a) Fav and had shortened, now I only back for the place (well, mainly) but this one was interesting for the win as well.

Another observation was that if the nag was a no bet and another contender had firmed into fav,...... this had an even better SR.

I had to let this go as the time spent in front of the comp was a killer.
