In this local universe, Patterns Rule!

(includes the real beginning of pattern = 9/70)
A numeric pattern identifies a Pi approximation closer than 355/113
(focus is on the decimal portion of Pi with +3.0 assumed):

What's the dividend/divisor that gets even closer to Pi?
(this pattern hints that an algorithm can be created;

go for 16 decimal digits!)
