I don't think I've ever fully understood how team prestige is calculated but I am really confused now.  Take the following two teams as an example:

Team 1
Most Recent Season: 24-5, 14-2 in conference, #9 ranking, 12 RPI, Conf Champ, NT At Large Bid, NT 2nd Round
Season 2: 20-13, 8-8, NR, 56 RPI, PI Championship Game
Season 3: 15-14, 7-9, NR, 97 PRI, PI 1st Round
Season 4: 13-14, 6-10, NR, 125 RPI, No Postseason

Team 2
Most Recent Season: 20-15, 7-9, NR, 38 RPI, PI Champion
Season 2: 19-12, 12-4, NR, 37 RPI, NT At  Large Bid, NT 2nd Round
Season 3: 29-4, 14-2, #6 ranking, 4 RPI, CT Champion, NT Elite 8
Season 4: 23-9, 13-3, #17 ranking, 21 RPI, NT At Large Bid, NT Elite 8

Both teams have a B+ prestige.  The only way this makes even the slightest bit of sense is if the most recent season is very heavily weighted whereas the others are not--but even then, this seems odd to me.  Feel free to tell me I'm delusional though (I've been accused of worse).

I included the past 4 seasons b/c I think I recall reading somewhere that these are the seasons factored into a team's prestige?  Maybe I'm mistaken?  Anyway, I'd appreciate your thoughts.

need more info. What division? what is conference prestige? what were the prestiges at for the other seasons (to determine how high or low these B+s are - not all B+ are the same - if one is just a tick over the minimum and the other a tick from becoming an A- they both show B+ but are not in fact equal...)

D3--both schools are members of the Michigan Intercollegiate Athletic Association (MIAA), 1 of only 2 conferences to have a B prestige.
