Mixing quality swill in a food trough

[Carebear]

So lets say you put in 1999 x 50/50/50 beets then add a 1 x 10/10/10 carrot. You will end up with 2000 10/10/10 swill.

Im pretty sure you will end up with 2000 49/49/49 swill, in fact.
If you put in 1960 50/50/50 and then add 40 10/10/10 one by one, you will get 2000 10/10/10 I think.

Good point, it will take more than 1 but the issue still exists. Thanks
