Pacing against recovery. The Finnisher wants the Battle to become inevitable; Miguel wants it to become plural. Their last four sanctioned meetings produced two appeals, one recovery-window protest and no change in personal philosophy.

Freestyle’s longest-running argument over whether difficulty creates spectacle or spectacle makes difficulty worth scoring. Judges usually answer with decimals. The crowd does not.

Power’s hardware rivalry. Big O forced the first sensor-headroom redesign; The Aftershock forced officials to decide how long a result can continue after everybody believes it is over.

Silence versus stillness. The Pacific Rim puts both Control philosophies on the same Major card, which has made the acoustics team more nervous than either competitor.

The Extreme division’s temperature war. They rarely compete under the same environmental code, which has never stopped either camp from insisting its conditions are more legitimate.

Multiples became less predictable when Rossi proved Miguel could be beaten twice. Their rivalry is measured as much in recovery intervals as wins.

One built a career below freezing. The other would prefer to remove the ground entirely. Their disagreement is mostly about what still counts as an environment.
