Yes, there is nobody debating that you pulling 3.5x your bodyweight is good.
Yes, potentially if you put in the proper work and train/diet smart.
I'm not sure where I said that 415lbs was an average pull? Additionally, I wouldn't consider an average lifter to be the same as an average COMPETITOR.
Like Vince said, doesn't this statement detract from your 'crazy' deadlift?
If it isn't evident to everyone reading, I'm quite bored at the moment hence the caring enough to reply to this thread...
