Thanks again Gary.

I think I understand what you are saying if a horse is scratched and why one in a particular column might not have sufficient points to move up the ladder.

But what I still do not understand is, forgetting about an individual column and taking the sum total of all of them why a scratching can influence another horses positioning in the ladder, unless their is something in the neurals that figures in something like head to heads.

Then if their is a scratching I can see some points changing for those horses that have raced against the scratching in the past.

But, I am not sure that is figured in, so I am none the wiser.

ps

Remember, I am talking about positions, not the individual points of each horse.
