It should be very useful,
gerry, as in most of the races I analyse there is no rock solid VDW class/form horse, so it is usually sit on your hands time re betting.
But almost every race has a VDW class/form horse, from the rock solid to the "I wouldn't touch it with a bargepole".
Only a guess at this stage, of course, but I think that on top of the 10%+ that are rock solid, there may be another 20% I seriously consider before, usually, leaving them. Copper Knight for the race on 21 May comes to mind among those I discussed pre race on the forum. He would of course not have been a winning "cover" but he was pretty sure to go close so, like today's, essentially a bet to nothing and a proportion will undoubtedly win. Great Blasket today was not as attractive from a VDW perspective as Copper Knight on 21 May, but with cover for up to three places in a six horse race at odds against, he suddenly took on a more appealing appearance.
The other race I've analysed is the 7.30 Windsor, where I see you have gone for Havanagreatime. I don't rate him as being a VDW form horse because of his last run. I had Sir Les Patterson as the VDW class/form horse, not a consistent form horse but only a touch short, but he is now a non-runner. Second on class/form I have Durham Castle but only 4th highest on the abilty rating and for a class dropper with not strong enough support key horse-wise. At currently odds on for cover, in a much stronger field relatively than Great Blasket faced, not for me, and hopefully Havanagreattime will win for you.
