Lets first take a look at what you REALLY have to do to make a Battle Road "worth it". First, you have to know your rating, and the ballpark rating of the people you're playing against. Next, you have to know the general amount of skill the people you'll be playing against will have. NEXT, you have to know the metagame. Finally, you have to guess at what you think your record will be at the end of the tournament.
I thought through all of the steps above, and decided there was no WAY it would be profitable for me to play any Battle Roads. I calculated that I could literally only take 1 loss a tournament, else I would lose a significant amount of points. When playing in the midwest, you'd be LUCKY to sneak away from a tournament with 1 loss. I can name 20 midwest players off the top of my HEAD that are EXPECTED to make the cut at Nats. So, yea, knowing that I could only take 1 loss against the toughest metagame in the world, I (correctly) opted out of Battle Roads.
Now we have players like Kettler, Ross, Miguel Angel Lopez Bernal, and Roberto Sora who actually SKYROCKTED into top 8 from Battle Roads. Why's this? Is it because Miguel Angel Lopez Bernal and Roberto Sora are actually TWO OF THE TOP 8 PLAYERS IN NORTH AMERICA? No, they're not (sorry guys, but it's true!). They are all actually high ranked because they find the smallest cupcake competition tourneys in the WORLD, and proceed to x-0 against a bunch of players who probably, no, DEFINITELY don't even know how to read. The players at the super small shops in super small cities are SO bad, that it's impossible to lose to them, luck or no luck.
