Recently @soylentqueen gave me the tiniest of glimpses into the world of competitive policy debate and oh wow I am still a naive idiot about this subculture but I am SO! FASCINATED!
First! Some of them make arguments at ~six trillion WPM?? Please listen:

These arguments draw on huge libraries of cards which they prepare in advance, individually summarizing various speeches, policy documents, positions, etc! Teams use these plastic tubs to transport these papers b/c they maximize checked baggage volume! nytimes.com/2010/04/18/edu… 
They "cut" 1000s of these cards by using a multi-level scale of underlining, bolding, highlighting, font size, etc to make the key points of a primary source rapidly visible on the page! There are plugins for word processors to help do this more quickly! chrome.google.com/webstore/detai…
The highlighting technique makes me wonder whether some of How to Read a Book's approach could be executed this way, surfacing the text's structural skeleton through levels of inline markup, rather than by making a parallel summarizing outline. I'll need to try these plugins!
Also: any claims one team makes which aren't specifically refuted by the opposing team are taken to be true! The fast-talkers are fast-talking to make as many claims as possible—and the opposing team has to track and then refute each one!
I still don't understand anything that's going on when I watch one of these things, but I'm totally fascinated and impressed! (And my apologies, @soylentqueen, for my inevitable butchery of what you described)
