But why choose high score and not average?
I think high score is more reliable than average score for most people. Look at @penguingm1, for example. His best score is 56 but his average is only 19.68. This is because he starts over when he has a bad start. I hear that many people do this.
And I bet that same impatience impacts their classic time control ratings on average to some degree

When I do tactics trainer, I can make a pot of tea and enjoy it while training. When I do puzzle rush, my tea grows cold. This is probably the main reason I haven't done puzzle rush more than 15 times.
Besides, I have a gnawing suspicion that it leads to superficial evaluations of positions.

True but, as an outlier, the high score is theoretically quite a high variance statistic for everyone.
A test is to compare the correlation coefficients between blitz rating and the two PR statistics.
@GM_Kenny_Ji How did you collect the data? Was it done manually, or did you write a script to collect data, presumably using chess.com api?

The ratings of people with the same puzzle rush best score vary by about 1000 rating points in the middle of the graph.

The two far right dots on my PR score's line represent the range within which rating usually falls, although it is in the upper half of the range 90% of the time. The rest of the dots represent ratings that I haven't had in years, and mostly that I had only on the way up. The line marks a spot where I was in 2014, briefly, after a loss of more than 100 rating points during a slump.
All this is to say that I don't rust the data.
Among other things, the data should be controlled for level of activity in both blitz and Puzzle Rush. There is no indication that such factors were considered.

I played for a few hours yesterday during the all day event, and by the end of it, I was not getting better, I was getting worse on average. Doing serial puzzles that long actually made me feel like rushing more and guessing faster on problems I did not immediately solve. It has the same effect as playing blitz, in that respect. I don't think this kind of ADHD-affirming mechanic is really good for getting better at the game past a certain point. It has diminishing returns and then starts to impede overall chess ability if abuse continues . Call it the Nakamura Effect, if you will.
I made a formula:
y = 40x + 520
y = blitz rating
x = puzzle rush 5 min highscore

I think it's quite accurate.

That would put me at 2040, 230 points higher than my best ratings. I suppose that could be some kind of theoretical ceiling if I were to put my back into studying and playing, because I am something of a "casual" player, but...dunno how accurate this is.

Nowdays 3 min highscore is literally the same as 2019 5 min highscore

that's SUPER ACCURATE for me! My high score in 5 min is 36, this formula gives me 37 for blitz rating of 2000

if thats the case, it will not be hard for you to pass
maybe you are weak in other areas
Maybe such people rage quit blitz games, too.
