Turning point

In Round 3, you committed to numbers that worked against you. Once you accepted the opponent’s framing on cost and salary, your position became mathematically vulnerable.

Where you lost ground

You answered the cost question directly instead of challenging the frame. By the time the opponent forced you into a single program tier, the contradiction was already loaded.

The one thing

Lead with the math before your opponent asks for it. Cross-examiners don’t just attack claims — they attack the numbers your claims commit you to.
