You're right, both achievements are huge.

That said, I'm not too sure I understand the line "the kinetic energy transfer at a 100 km reference altitude is what matters"...

What is the "kinetic energy transfer at 100km" ? Why not say that what matters is the "kinetic energy transfer", period? It doesn't make any sense to me to put it the former way.
