Why "getting faster" and "getting in shape" aren't separate projects

The instinct is to split these into two boxes: speed and power belong in the weight room, the gas tank comes from extra rounds and drilling. Reserve theory says otherwise. Raising your speed/power ceiling is a conditioning intervention, because it shrinks the relative cost of everything below it. A more explosive grappler works at a lower percentage of max at any given pace, meaning more left in the tank than everyone else grinding at the same output.

This is also why chasing conditioning through volume alone has a limit. If your explosiveness never improves, neither does your reserve. You can add rounds all day and still be working at 80%, just tolerating it longer. You haven't changed the number that determines sustainability; you've only gotten better at enduring the cost. Raising the ceiling changes the cost itself.
