| 3 | 482 | 0.796 | 60.6% |

Now the total validity for all rounds was 8.975. Pilots were allowed to drop their 20% worst scores, which is equivalent to dropping scores from enough rounds whose validity totals 1.795.
Scott's worst round was round 7 when he was absent (validity 0.680) so he still has to drop another 1.115 worth of days.
His next worst round was round 4 when he performed at only 47.1% of the maximum possible. Round 4 had a validity of 0.611 so he still has to drop another 0.504 days.
His next worst round was round 9 when he performed at 51.3%. However round 9 was worth a validity of 1.000, so he only has to drop 0.504/1.000 = 0.504 of the day and can keep the other 0.496 of the day. Of the 513 points he scored he has to drop 258 of them.
Hence Scott has to reduce his total score by 0 + 288 + 258 = 546, leaving him with a total of 4788.
