You could make it more complicated than the mode. If one team had say 10 red, 1 amber, 12 green, would you want it to return green or amber? Because I would say amber for that but the mode will return green
I have done a similar red amber green thing and worked out the overall mark by assigning 1 point for red, 2 for amber and 3 for green, or something like that, then averaging. So like, for each item in col B, add up the equivalent in col C plus 2x col D plus 3x col E, divided by the sum of c:d for that row, then stick that inside an IFS to say if it’s <1.5 it’s red, >=1.5 and <2.5 it’s amber, >=2.5 it’s green
