Ryu's Bone Structure was one of his strongest trump cards, but it was also one of the talents that he had the most difficulty in learning to use. This wasn't just because its appearance in himself was a first across Existence, but also because the paths in which it could take were too numerous.
The Cosmos Fog within him's main purpose was separating from the influence of the Heavens. This sounded great, but it gave him too many paths that he could take.
The logical thing to do was to just focus on the Space and Time aspects of it, and he had.
With his Cosmos Fog, he was able to use Time acceleration in ways that others couldn't imagine, even to the point of ignoring the distortions in the laws to comprehend insights with time on his side nonetheless.
This benefit alone was shocking because the one thing that Ryu didn't have the benefit of was time.
