EXTREME Knockback Problem

[HM04]

I run a practice pvp server and the knockback problem is horrific. I am trying to good smooth hit detection, and controlled knockback. Not too far, not too little. Just right The default hit detection with my Spigot 1.8.8 Jar is good, but the knockback is way too far. I tried installing the plugin Knockback fixer, and it is very buggy and not good. I had my dev create me a custom fix for the knockback and it didnt work out. Do you guys recommend a certain jar to fix this? Thanks

You do not need anything, all you need is a keyboard. Hold F3 and press T. It will reset your minecraft data and fix your bug.

I run the server, I am not trying to improve my knockback on the server. The knockback is bad for everyone.
