Horses moving up after a loss

[Lt1]

A while back I was listening to the Tom Brohamer tapes and during the contender selection part Tom stated that although horses moving up in class were not automatic throw outs they were not a good betting situation. I finally got around to doing a survey on 100 such animals and here are the results

Horses wins places shows off board
100 13 8 3 76
To me this survey, based on the percentages, makes this type of horse a throw out in my book.
Wishing good skill to all.
