puzzle rush score (5 min) vs OTB rating strength ?

i looked . at it and my average is 19.99 

i did the math myself because my average is fake bc theres alot of times where pr just crash ed

This is more accurate. 

The problem with your list is that you're basing it on records, not average. For example, your average is 17 yet you're 1700 but according to your list you should be 1200 rated. 

Averages are useful, but most members here rage quit after getting an early puzzle wrong, so they might not be very reliable.

One slightly amusing thing about @gserper's article is it was before young Dutch and American masters demolished the top end of the scale, with 105 being the current official top.

The scale is definitely for best scores. Otherwise the GM himself gets demoted to (non-master) strong tournament player!

It is already outdated?!

As a general guide, it can't reasonably be outdated in a few months (can't be more than that). The new records make no difference to say the range of scores for GMs. Note there are other masters of all types above 50 as well.

i have new record of 28 but my blitz is still at 1330....

25 puzzles solved = 1400 blitz 
30 puzzles solved = 1800 blitz 
35 puzzles solved =2000 blitz 
40 puzzles solved = 2300 blitz
45 puzzles solved = 2500+ blitz

60 puzzles = Stockfish

105 puzzles = IM Casper schoppen lol

Too high, I have friends who are 2200 both online and otb and can't get passed 30. Also, you've got to specify whether you're talking about average or highest score because they're both very different. 

For example, your highest score is better than mine, mine being 29 and yours being 39. Yet my average score is higher than yours, yours being 16.54 and mine being 19.95. Your attempts are also way higher than mine with a whopping 3431 compared to my 80. 

This is interesting to compare because I do the same.  My best at that time (January) was 28 and my average just below 21. With 6 months more, Vicariously-I has got his average up to 24.55 and his best up to 32, while my average is 22.15 (>23 in the last 100) and my best 31, so he remains slightly more consistent than me, with almost exactly the same improvement in best and average.

I suck badly at this.

Yeah cool I guess we have both improved our best and average. I was stuck on 29 for a while but now I can't seem to break 32. I came close a few times today though taking advantage of the 24 hour unlimited puzzle rush.

Where did you get that data? That does seem to offer prospects for a degree of correlation, contrary to my claim.

But why choose high score and not average?

Average can be inaccurate for people who quit immediately when they get one of the first few puzzles wrong, see for example https://www.chess.com/member/hallvardhf , https://www.chess.com/member/anthonyatanasov , https://www.chess.com/member/wolfbewwi

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.
