We are higher in about every category
Puerto Rico Cayey 4-4 vs top 1-50 RPI  5-1 vs top  51-100 RPI Beat #4 RPI team - My team

Johnson C Smith 4-5 Vs top 1-50 RPI    6-0 Vs top 51-100 RPI  Beat # 6 RPI team and #11 RPI team

Is it the key wins?

Other categories ( I think there are 10 in all)  are considered as well.  Road record, record in last 10 game, non-conf SOS,  Conference SOS, etc.

Our ranking, RPI, last 10 and SOS are better. 

Mind boggling, huh? Welcome to WIS.

I honestly don't know what is considered, but after a quick look, I think your team should be slightly higher.

Based on just what you posted I think an argument can be easily made for JCSmith.  And that's quality wins.  Two wins over Top 11 RPI teams versus your 1, 6-0 versus 1-50 versus your 5-1.  You've got the slightly better RPI, but I think some of that is due to your 10 road OOC games.  I think rightly so the projection report is weeding out the road win bump that the rpi doesn't.  Especially at d2 and d3, HCA isn't very significant but the rpi formula still awards a 1.4 weight whether a team wins at Bethany or Duke.  With what I've seen of the projection report and new selection criteria, I am very impressed with the decisions it's making. 

Real life selection committee looks at 1-50 records much more than rpi and I think so does the projection report committee for HD.

At the end of the day trying to separate teams from one another when they are less than 10 spots apart is like splitting hairs.
