You're pulling numbers out of nowhere.
There is nothing to suggest that Ichigo got at least 10x faster much less hundreds of times. Gins bankai doesn't expand and that was stated on Panel mid fight.
You can't scale Ichigo off of Kenpachi just because they are in the same tier. Kenpachi has the best physical feats in the verse. Maps had to be redrawn from a side effect of Hashi and Madara's fight. Once again, Ichigo has no feats suggesting he can damage a PS.
Show me where Ichigo has taken mountain level blunt force attacks before. Show me where he has shown blunt force durability far above Madara and Hashirama.
