Your math is off; %62.5 of 14 is 8.75. %56 of 14 is 7.84.
But we're not working with 14. We're working with 8. You explicitly stated earlier in the thread that you felt we should take Sanders' bonus delegate from the poll that decided the destination of eight delegates, so that is what we are doing.
I would take one delegate from the first poll. Problem solved.The source of this issue is that there's not one poll for fourteen delegates here, there's three. There's one poll for eight delegates, one poll for four delegates, one poll for two delegates. In Wyoming, it happens that all three votes are contested using the same vote, and in each of those Bernie did not get a sufficiently statistically significant enough win to gain an extra delegate.
For what you're asking for, you have to answer the very important question of which poll do you take that extra delegate for Bernie from? That's not insignificant, there are actual people attached to all this.
