There is a bias against recent success in a program. Conversely, the "proven" programs get the AP votes. On the other hand , Wayne did defeat Fairmont early in the year and their only other loss was to the number one team. I prefer power rankings by a computer over human votes. Maxpreps has Fairmint above Wayne likely due to the wide point margin of their victory over them in their most recent meeting.
Speaking of Maxpreps, they have one AP #1 ranked as low as #11 in their division and #80 in the state.
Another thing I have noticed over the years is a bias for North East schools over other areas of the state. Maxpreps makes those corrections as there are enough crossover games these days to get a better computer reading of real vs percieved strength.
Dont let it bother you too much. The two state championship teams I have followed were not highly ranked in the AP, but did just fine in the tournament knocking off multiple higher ranked teams along the way. That's way more emotionally satisfying than losing to a team the poll says you should beat.
