Well, it will only be the last 3 spots that are (substantially) affected by 3 cheaters - everybody else either qualified or failed to qualify anyway.
And the luck I'm referring to is in timing. If you look at the scoreboard for round 1B, 1000th place scored 34 points and a time of 1:30:38. 1001st place 34 points and a time of 1:30:48.
Also, for the last 3 spots out of 1000, there is a lot of luck involved anyway.
