Odd WCA stats/ Stats request Thread

Talking about long PB streaks, I've set a new 3BLD single PB at every comp I went to except my first comp, for a total of 8 comps. Is this some kind of record?

Your request for the record sounds needlessly specific to me.
You want a list of people with the longest unbroken streaks of 3bld pbs in each comp, but not counting the first comp?
That last part is a pointless get-out clause.
What about people who go to comps that don't have 3bld in?
What about people who had a really long streak but it's now broken? After all, it becomes a near-impossible task once the streak reaches a certain point.

Didn't mean to make it sound like I'm attacking your request - just clarifying and trying to get some reasoning

How about top 10 most sub-30 FMC solutions in a row?

My idea was about longest unbroken streaks of PBs in a certain event (not only 3BLD but considering one event at the time). Streaks that are now broken are fine. I didn't take in account that we might consider or not comps not holding that event to break the streak, but for me it's the same. My point wasn't that I got a new 3BLD PB at (almost) every comp, but that I've kept improving it for 8 comps in a row.
I thought I've seen this stat a few pages ago, but now I can't find it.

So the last time Sarah Strong didn't DNF any 3x3 solves in a comp was Toronto Summer 2012. Lol.

 

[JackJ]

What's the mean of all 3x3 solves in the database? What's the standard deviation?

Thanks! Can you also list the percentage drop for each cuber please?

EDIT: I mean from their most recent pb average before their first sub 9 average, not their first sub 10 average.
e.g. If a cuber's most recent averages were 9.9, 9.8, 9.7, 9.6, 9.5, 9.4, 8.9, the drop would be 0.5 not 1.0

Hmm that's very cool! Is there anyway you could give me the same data without the outliers? I'm doing a project in my stats class and that SD is not very workable with.
