Yes. I actually think you are wrong. It worked this time, but it doesn't always work. And if you continue to pat yourself on the back when you get lucky, and fail to modify the things that are wrong (i.e. the same things Lovie has ignored for the past 3 or 4 years), then yes, the problems in this type of win DO matter.
Having said that, of course, I'd rather be lucky and win than perfect and lose.
