Speedrun.com is not a good way to know what all the current singleplayer IL (individual level) WRs are on Hot Pursuit because not everyone submits their runs (or even knows of speedrun.com's existence), as well as not every legitimate run being leaderboard valid - so it's best to check the spreadsheet linked below as it lists all of the current records and is regularly updated.
