There's been a bit of opinion expressed here on the how and why of Peter Trueb's computation. I believe that all record pi computations from 2010 on have used Alexander Yee's "y-cruncher" on home computing systems (Peter Trueb's can likely be had for under $40000 U.S., the cost of some automobiles). So the why is obviously because such a program exists and has garnered now-five records. As for the how, Peter states that the Chudnovsky formula is used by y-cruncher: http://pi2e.ch/blog/2016/07/30/the-chudnovsky-formula/ An overview of y-cruncher is available here: http://www.numberworld.org/y-cruncher/

Sadly, the information given by the program author is rather sketchy.
