We don't know who it is, but I believe it is the same user that joined during the Pentathlon. And yes, they are one heck of a powerhouse!
BTW, the user was already with us
before Pentathlon, and helped us during the entire duration of Pentathlon 2020's Rosetta@home Marathon. (Those who are really curious can find this user's Rosetta@home performance during Pentathlon in boincstats' table of "Last 60 days", and their performance at the 11/2019 Formula BOINC sprint at Rosetta@home in FreeDC's table of "recent milestones".)
On another note,
here are our results at Rosetta@home sprints at Formula BOINC, complete since the introduction of the sprint format:
05/2017 ........ 2.0 M ........ Gold in League 2
06/2018 ........ 3.4 M ........ Bronze in League 1
11/2019 ........ 7.7 M ........ Silver in League 1
06/2020 ........ 7.5 M ........ Silver in League 1
I think it's fair to say that TeAm AnandTech's performance in Rosetta@home contests has been
pretty good recently. :
-)
Our 2020 result was of course somewhat impacted by work scarcity during ≈2 of the 1+3 days. But Gridcoin for example dropped from 10 M in 2019 to 8 M in 2020. While this may have various causes, their output before and after the shortage points to the task shortage to be the major or only reason for their reduced performance this year.
Oh, compared with the 1+3-day sprint results above, our 29 M at the Rosetta@home Marathon of Pentathlon 2020 (3+14 days) are rather excellent. That was 1.7 or 2.1 M/day average, depending on whether you divide this by 17 or 14 days.
