The record, in short

What the tape says about how Julian argues and how the claims held up. Everything they said, and everything said about them, is in the tabs below.

How they sound: not measured why? →

We measure speaking style by listening to the audio itself, and a fair number needs at least 2,000 words from one person on tape we have measured. There is too little of Julian Gargicevich on measured tape to publish a rate. This says nothing about how they speak.
