Credit to this post goes to CheapHead from another site: Everyone gets very confused about knockback. Low ping players think high ping players take no kb and high ping players thinking the same of low ping players. Knockback expected from low ping players: It should be normal. Looking at a player with low ping's knockback from serverside it should be relatively normal. Knockback from high ping players. It should be relatively normal just a bit delayed. Because it is delayed it looks like they take more than they should looking from first person because the combos are generally longer. Neither of these two players actually take more or less knockback. Lagging players, players who lag and fail to send packets aka teleporting players. Their knockback is actually messed up a lot. What happens often is they get hit a lot of times and then when they finally get caught up back to the server they take it all at the same time. But because getting hit 3 times in a row doesn't do 15 blocks of knock back the amount they take in total is reduced. They think they take more knockback but in reality they take the least. Cps: Cps effects knockback a great bunch. Whenever the player sends an attack packet their total velocity is slowed. This includes knockback taken. Each hit multiplies velocity by 0.6, I am not sure how long it lasts sadly. However this number stacks with more and more hits. If you get 2 clicks in this time frame you get 36% knockback. Because high ping players have a longer time before they take knockback they can hit their opponent a few times thus reducing the knockback they take. I hope this helps. Why does this have to do with skywars? Knock back can be especially important in skywars and many players complain about it here the most.
