The only numbers I ran on the first round were PDL vs. NPSL. (PDL teams went 5-3-1 against the NPSL, advanced in 5 of 9 matchups and are 20-15-4, advancing in 21 of 39 matchups, since 2014.) Haven't had time to run anything else, and newtex has more.
yet another win via protest: http://charlestonbattery.com/news/villages-sc-disqualified-battery-back-in-usoc/
Two results -- Ventura County Fusion over LA Wolves FC and The Villages SC over the Charleston Battery -- were overturned because the winning team used ineligible players, while two other protests from Kraze United and San Francisco City FC regarding the use of ineligible players by The Villages SC and CD Aguiluchos USA were rejected because they weren't filed in time. http://www.socceramerica.com/article/69017/us-open-cup-nasl-usl-battle-resumes.html?edition=15646
