JAKARTA - A 15-year-old Bali resident set a new Guinness World Record for memorization over the weekend, breaking a record that he previously set three years earlier, local media reported on Monday.

Performing before 2,000 participants at a leadership conference, Dominic Brian Hindarto managed to memorize 84 non-binary numbers in less than a minute, beating his earlier world record of 76 numbers set in August 2009.

It took him four attempts to top his earlier mark, after coming up short in his first attempt and getting distracted by power blackouts during the next two attempts.

"I flubbed it a few times, but I persevered and kept at it, and finally I did it. At the end of it, I was physically and mentally exhausted," Dominic was quoted by the Jakarta Globe as saying.

Bob Foster, a representative from Guinness World Records, said that despite his young age, Dominic deserved to be called the " Grand Master of Memory."

"The record that he broke has already been viewed by thousands of people on YouTube," he said.

His latest feat makes Dominic the holder of two Guinness records: one for the most non-binary numbers memorized in under a minute, and the other for the most binary numbers memorized in under a minute, at 216.

He is also recognized by the Record Holders Republic for being able to memorize 90 numbers and recite them in order, in reverse and at random.

At the end of 2011, he participated in the World Memory Championships in Guangzhou, China, representing Indonesia, where he won a bronze medal.
