People have been obsessed with memorizing the digits of pi for a long time.
Akira Haraguchi holds the the current world record of 100,000 decimal places, set on October 3, 2006.
Akira broke his own previous record of 83,431 decimal places, which was set on July 2, 2005.
Finally, Hiroyuki Goto held the record previous to that, having memorized a mere 42,195 decimal digits of pi in 1995.
Your Task: Find the "best-fitting" line equation for this situation, using year only (i.e. ignore months) as the independant variable. Now, when would you predict that the 200,000 decimal digit record will be set?
