Breaking a tie- Cross Country scoring excel sheet

I am building an excel sheet that will score cross country meets. I know there are apps and software you can buy, but I have learned a ton of excel by making it myself.

I have an excel sheet that will score 8 teams perfectly. However, I cannot figure out how to break a tie. Without going into too much detail of scoring a meet. here is what I need. See the picture for reference. Teams are ranked in column M, team names in N and scores in O. As you can see two teams have a score of 75 and are both ranked 2nd. In cross county there is no tieing. You break this tie by which teams 6th runner came in first (runners 1-5 make up your score so if you tie in score of runners 1-5 the tieing team with their 6th runner finishing first wins).

I have each teams 6th runner's place in column P (note some teams may not have a 6th runner and this should be taken into account).

Basically I need to re-rank any ties in column O based on the lowest number JUST BETWEEN THE TIEING TEAMS in column P (the 6th place runner). My problem is I cannot figure out how to write a function that only breaks the tie and reranks when there is a tie. I do not want all teams reranked based on the 6th runner.

Any help here would be gladly welcomed.

This did not rerank based on column P.

This is what I need it to do.
1. Recognize any ties in column M
2. If any 2+ teams tie in column M rerank among the tying teams only based on lowest number in column P
3. The rerank should not interfere with any team not originally tied in column M
4. Therefore if you look in the image for reference schools Ben Franklin & CP Taft tied in column M with 75 points for a tie of 2nd place. Therefore those two should be reranked among themselves based on column P (6th runner).
5. This formula should then rerank Ben Franklin #2 because their runner (27th place) came in before CP Taft 6th runner (40th place).
6. CP Taft should then be ranked 3rd. (As you can see the formula I'm currently using skips 3rd place because of a 2 way tie for 2nd place which I am attempting to eliminate.
