When comparing more than two options most could be significantly less than half (e.g. if I have two red balls, and one ball each of blue, purple, green, orange, pink, and yellow, then the color I have the most of is red, despite representing only one quarter of the total balls.)
That said, any attribute attaining more than half of the pie must be most.
