It's possible to use a phyton+numpy program in 20 years, but you also have to save the entire environment and make sure that it works air-gapped (otherwise external dependencies would fail). One possiblity would be to store it as a qemu virtual machine. It's very possible today to boot up stuff as VMs that is 20 years and older (e.g. 20 year old Linux distros or Windows XP iso from early 2000s).
To be precise he was 2484 in 2021-Jan as you can verify here https://ratings.fide.com/profile/2093596/chart
Hence he went from IM level to Super GM level within 1 year and 9 month.
Another coincidence is that GM Maxim Dlugy, a coach of Hans, is a known cheater.
And there's the incredible sharp increase of rating, basically from 2400 IM level in 2021 to Super GM 2700 level (live ratings) within 2 years. Yes, that is legitimately possible, other players had similar incredible gains, so it's not completely unheard of, but he is either one of the greatest improvers of all-time or something is wrong.
Two sided un paired t-test.
T-value of 4.9. SE of 56.325
Group 1 mean of 2383 with sd 125.56. Group 2 mean of 2659 with sd 119.16 39.7 SEM.
P value of 0.0001.
By conventional criteria there's about 0.01% chance the differences in the means is due to chance alone. That's 0.0001.
I.e. If you were to play 19 tournaments randomly 10,000 times, only 1 in 10,000 would you perform better on live boards as well as Hans did due to chance alone.
> The radar intercept officer in the rear seat, Lt. Matthew Klemish, initiated ejection for himself and Hultgreen as soon as it was apparent the aircraft was becoming uncontrollable. First in the automated ejection sequence, Klemish survived. However, by the time Hultgreen's seat fired 0.4 seconds later, the plane had exceeded 90 degrees of roll, and she was ejected downward into the water, killing her instantly.
It seems that she was just 0.4 seconds too late, otherwise she could have survived like Klemish.
