There are some errors in your summary:

Netero mastered the outspeed of sound when he was fifty years old, though it is unclear when he got down of the mountain, it is likely that it was when he was fifty, so he is one hundred and ten years old.

Neferpitou's Nen Ability, Terpsichora, allows him to attack a TENTH of a second after it is conjured, that's how fast Netero is. Also Neferpitou heard his thoughts, Netero wasn't actually talking. As Zeno stated, when two persons' percepcion of the time are fighting, they can somehow read each others' thoughts.

Also, Netero didn't challenge any random dojo that was near, he challenged the Shingen-Ryu Kung Fu Dojo, where he originally trained and reached it's peak as martial artist. Note that, Wing and Biscuit both were trained in this same style of Kung Fu.

And I guess that's just it.
