First you say Oda apply no logic then you go on to use logic (flawed logic) to suit your headcanon to say it will only be hypersonic speed?
Oda described it as Lightspeed, stop with the terrible headcanon. There is only three options for you?
1. You apply logic, which means Zoro dodges Lightspeed because deflected compress air at that range would still travel at lightspeed.
2. You don't apply logic, which means you accept manga logic, meaning that Zoro dodges lightspeed because Kuma described it as being deflected at lightspeed.
3. You take your L silently and become a follower of the Grandmaster.
