Okay, why not, I looked at Spencer's non-district opponents. Spirit Lake (6-2) has a good shot to defeat Garner-Hayfield-Ventura (3-5), and Humboldt is likely to win over 0-8 Perry. So wins by either Webster City (over Boone) or MOC/Floyd Valley (over Okoboji-Milford) would probably boost Spencer's RPI a tad. If they both lose (so their non-district opponents go .500 for the final week), it'll probably drop a little, which gives Washington or Mount Pleasant a little help.
Again, not considering OOWP at all, except for 3A opponents.
Obviously, the biggest factor in RPI is your own record (each game accounts for 11% of your own winning percentage factor, while each game by your opponents accounts for 1.2% of that OWP factor). But when you're talking about the difference between .5772 and .5890 in RPI, that doesn't take a whole lot of movement to send one team to the playoffs and have the other stay home.
