I surveyed 100 cubers and found an interesting trend

A ran a small survey on the Cubers discord from July 2023 to April 2024. I waited till I got 100 respondents. Finally posting here and not just discord since people seemed interested in this first result: a way to predict your PB single based on your Ao100 PB.

This graph gave me the following empirical equation.

If you want to compare how close this is to reality, I'll arbitrarily suggest the following formula. This is how much the predicted PB is off by.

NOTE: If you average faster than 7 seconds or slower than like 20 seconds, I can't make the claim that the Predicted PB equation will be very accurate. Well, I can't ever make the claim that it'll be accurate for you specifically... Statistics, yay!

I ran this survey to look at cuber consistency. I've seen many people claim they are inconsistent. Comparing people's average to their standard deviation reveals a moderately strong correlation.

Your average is probably the biggest contributor to how consistent you are. You're better off looking at your Coefficient of Variation (standard deviation divided by average) if you want to compare your consistency with people. Make sure you all are using the same deviation, like the one from CSTimer, and using the same average, such as Ao100. To see these kinds of stats on CSTimer, click on your solve count.

The survey also asked about cuber's honesty when doing solves. From this, I can make the claim that most people think +2s and DNFs count at home.

Disclosures:

  • I removed several respondent answers based on if I thought the numbers they gave were feasible.
  • One user reported a standard deviation of 40.7. Based on the other data they reported, I assumed they meant 4.07
  • I responded to my own survey
