USA TODAY Sports Arkansas-Little Rock Trojans

Was your bracket perfect after Day 1 of the NCAA Tournament? If so, you're part of the lucky .01 percent. Just 16 games into the tournament, 99.99 percent of all online brackets were busted.

Fans can thank a quartet of double-digit upsets for wiping out most of the field: Both 12-seeds and 11-seeds playing on Thursday won their respective games.

It only took a few hours for 99 percent of fans to see their hopes of a perfect bracket dashed. Yale's upset of Baylor was picked by only 20.3 percent of brackets played in ESPN's March Madness challenge. By the time Arkansas-Little Rock buried Purdue under a barrage of late 3's, 99 percent of Capital One's Bracket Challenge entries were broken.

Then, late at night, 11-seed Wichita State upset 6-seed Arizona, while 11-seed Gonzaga overwhelmed 6-seed Seton Hall.

By the end of the night, Yahoo Sports reported that just .00129 percent of its bracket entries were still in perfect condition.

One interesting note: Thanks to heavy fan confidence in the Zags, there would have been even fewer perfect Yahoo Sports brackets would have been busted if Seton Hall had defended their favorite status and held off the Bulldogs.

So if you're one of the elite few that got every game right yesterday, raise your glass and celebrate yourself. Because it's 99.99 percent likely you won't be able to do the same after Friday's games are in the books.
