Again, Truman, since you breed them to each other, the percentage does not go 
down.  If you could cross them out to Tarpans, Great Forest Horses, or 
Przewalskis, then yes, your premise would be correct.  But as you are 
breeding a mix to a mix, you still maintain a mix.

Try this.  Mix half whiskey and half Scotch.  Do this several times.  Then 
take all your half-and-half mixes and divide them in half, and add them to 
the half you've divided off of another original mix.  I guarantee you, no 
matter how many times you do this, you will never end up with something that 
resembles either pure whiskey or pure Scotch.  The only way you will get 
there is to use the pure form of one or the other to continue the mixing 
process.  That's why your model works great for pure breeds such as the Arab 
when dismissing the stray ringer behind the barn that occurred a couple of 
hundred years ago--since the offspring were consistently bred back to 
straight Arabs, the influence of that stray cross is halved with each 
generation and eventually becomes rather insignificant.  (And no, I won't 
join the "purist" crowd and try to maintain that such crosses "never" 
existed--that simply isn't practical.)  However, when you consistently bred 
crossbreds back to each other, you continued to get a mixture--and that is 
what has happened in the breeding of most modern breeds.  If you happen to 
enjoy that mix, that's wonderful--but what is the point of denying the 
contents?
