What happens after half-time — row = HT result, column = FT result
Each cell shows the match count and its share within that HT result row. Darker = higher proportion. Diagonal = result unchanged; off-diagonal = swing.
Team lead retention — when a side led at HT, how often did they win, draw or lose at FT?
Only teams with 3+ half-time leads included. W = won, D = drew, L = lost from a HT lead position.
