Very likely this is bull, probably just a rehearsed scramble. On the off chance it isn't, it looks as though it is just speedBLD which can't be termed as your 'own' method.
Did you expect that no one would doubt you getting an amazing time, in an event that has rarely been done, claiming to be using your own method without a sentence about it?
