Actually, the answer is 3
Look at this poster before 2013 Asian Football Championship, the score will be 3:0

Nothing against either Borwein, they are brilliant guys.

You did not read about the billion decimal places of pi?

No. What was it?

By the way, I am getting

for the first 41 decimal digits.

Surely you have seen that idiotic example the Borweins came up with?
