Although this data sheet is now slightly old news...what is this black magic that puts my team's OPR above 341, 365, 233, and 379?

Last time I checked, 3941 was ranked 262...quite frankly, I am astonished by this considering our current regional ranking. What factors go into OPR that could produce such a result?
