Find the winner and percentage difference between two teams

I want to find the winning team based on four different scores between the two teams.

I want to output which teams that wins and what the percentage score difference is.

I am not sure about how the percentage difference should be calculated.

See attached workbook for more information.

There are different max scores for the five different routes. Ideally, I would like to enter the max score for each route and then calculate the % difference!

Desired output is:

Teamname ( % difference in scores between winning team and runner up)

Ex.

Walkers (75%)
Runners (49%)
