In every qualifying session where exactly two drivers of the same constructor set a position, the driver with the better qualifying position takes one win. Constructor is determined from that same round's race-result rows (qualifying has no constructor field on its own); a driver with a qualifying position but no race-result row that round (e.g. a DNS) is excluded from that session's pairing rather than guessed. The ranking orders drivers by wins, then by win rate. The record is shown as wins–losses. Ties beyond win rate are broken by total season points, then alphabetically.
