It's certainly been a burden for western Canada for many decades, I think. As I say, we had the fortune of eliminating that in eastern Canada in 1989, and within a very short period of time we saw substantial increases in yield. As we indicated in our submission, in the last 15 years we've seen a 62% increase in wheat yields in Ontario, largely because we didn't have that burden of having to meet kernel visual distinguishability.
