To be honest, all you have to do is get a partner that lives close to you, and you'll get him 99% of the time. I did it at 11AM for me (6AM for Americans) and I got my boosting partner 24 out of the 25 times. I got a random for my 9th fight, but I quickly dispatched him.
Edit: I think I beat that Britalian guy several times when I was randomly playing online.
