Duel mode aims to put you into a race against another player with a similar amount of Cup/Division Points and, therefore, similar ability to yourself. The Performance Indicator (PI) value of each player's F1 car is not taken into account during the matchmaking process.
There is the possibility during matchmaking of large differences in Cup/Division Points between players being matched together. This is rare but offers you the opportunity to earn/lose a large amount of Cup/Division Points or have very little to lose/earn.
