in speedcubing, if the puzzles are randomly generated, how do they ensure that record times are performed on the same level of difficulty?

If the previous record was 5 seconds and the newst record is 4 seconds, how would it be fair if one competitor received an easier combination to solve?

They make sure you need at least a certain amount of moves to complete the puzzle. Otherwise you would get a 0s record just by getting a completed cube as the starting point.

Every combination.. if sufficiently scrambled can be solved in 19 moves

Scrambling sequence is randomly generated.. this ensures random equal chance to everyone

In order to get world record, you need to solve it several times and your time is averaged.

I’m relatively new to cubing, but my understanding is that at any given speedcubing competition, each competitor competing in a given category receives the exact same scramble. And the scramble is generated by a computer algorithm that helps ensure that it’s not too easy.  So when they’re directly competing against each other, it is fair, nobody gets an “easier” scramble.

When it comes to world records, yes, it’s possible that the very best single solve world record might have had an “easier” scramble (I’m not knowledgeable enough to know if it actually was), but cubers typically pay more attention to average solve time over a set number of solves (like 12 solves) in order to help even out the effect of a particularly fast or slow solve.
