I suspect the limiting factor is how fast the announcer can speak the numbers!

No contest. Soroban guy win.

If you watch the video in full, at the end (7:45) it had a "flashing numbers" contest.
15 3 digits numbers flash on the screen in ... 2 seconds !

There is no time to do any input, abacus or calculator.
They had to add them up in the head.

I cannot even count the number of flashes !

Counting the number of flashes is easy; however, extending the vstq to 15 items instead of the usual 3–7 items is the real push. I've found that I have a fairly short "very-short-term-queue" of about 4 items, I can push it to 5 sometimes. In addition, I can't add two numbers (of any size>1) as quickly as they can add fifteen 3-digit items. I'm out.
