Here is screen shot to help clarify my survey post
If you look under VDC% column you will note that the 1.5.7.8 all have %s under 3.5 while the 2,3,4,6 all have %s above 3.5. My survey found that you can downgrade the horses above above the 3.5% level and be ok 75% of the time. If you raise the bar to 3.8% you increase that to 79%. Hope this clears up any confusion I might of caused.
