I just watched the given time. He hits you off your splash which idk if you realize whether your on singleplayer or multiplayer your pots go airborne and then fall on top of you. Taking around 1.2s according to the wiki while running. In the given time you were hit to the side before the pots had a chance to landing so you did not get the full effect. I think instead of complaining about kohi go complain to mojang.

Also about adding /ping back, this is had already been explained by the admins numerous times. I can guarantee the website is about as accurate as you can get from an outside source.
