That sentence is just nonsense. One can get "close" to pi/2 with any
number of finite sums.

Not really. With an 11-term sum you should be able to get much
closer than you do.

Also, why do you add 6 extra terms to your sum that *increase* the
error by a factor of more than 20? The 5-term sum is much closer to
pi/2.
