My bad, I miss read what you said. Thanks for restating.
I can only guess that its an issue with the GUI causing delays for producing blocks and therefor not suitable for a delegate?? Not sure how the voting for ones self fits into it though.
I don't think there is any conflict in someone voting for themselves. It makes perfect sense to me and I expect it. The larger the stake someone has the more interested they are in maintaining a proper system. Why would they be expected to put that faith in someone else when they are doing it themselves.
