Extension Chains
Practice carrying one argument through all four speeches: the constructive version, a rebuttal frontline, a summary extension, and a final focus version.
Pick one contention. Deliver it four times, once as each speech would carry it: the full 60-second constructive version; a 30-second frontline against an imagined attack; a 20-second summary extension with warrant and weighing; and a 15-second final focus that writes the judge’s ballot.
Every version has to include the warrant. "Extend our economy argument" is not an extension. Re-explain why the argument is true in one sentence, every time.
Run the chain daily with a different argument. Within two weeks, PF’s shrinking speech times stop feeling like a constraint and start feeling like a rhythm.
