Dutch Bottom up Book Value%

[PantherSports21]

I want to Dutch multiple selections bottom up (regarding odds) to a specific book% value. So for example in a 10 runners race I want to Back Dutch all secletion starting with Rank 10, 9 etc. until I reach 55% book value. Can this be automated?

This should help as it does the same but with the front 3 runners so wouldn't require much editing to change to look at the back end of the book

The reply in this post from Jimibt will explain how to first find the number of runners in a race
