[There are reasons why SOLDIER took a lot of their downtime in performing squats. Not only to reduce the burn of fatigue, but often their mako-enhanced states left an abundance of energy left over after a fight. Still, Sephiroth recognizes that very obvious arm-pump Cloud performs.]

Hm, it seems that future proficiency comes through regardless. Even if it might still be premature.

[Blunt and honest. All Sephiroth, except for the softer edge to the words as he doesn't mean them harshly. Cloud's technique needs work and he thinks that Cloud already knows that, but swinging those swords around the way that he was, it takes some strength and not to mention the determination not to just switch to something that might be easier.]

It's impossible to tell that particular benchmark.
