Delay?

hey guys i wanna ask one thing. iam HNS player so its little bit offtopic. we were testing the HNS and we noticed that when iam on ladder and my friend will jump on that ladder. i see him 5 meters under me but he sees it like we are on one place. is there any solution for this like any console command or so?

my pings on that server are about 5-10, yes interp changed to 0.01 helped a lot
screens on ex_interp 0.1

can you help me with other commands that can improve my gameplay experience? jumping tweaks and things that help me with knifing people.
iam using basic commands for HNS like cl_sidespeed and edgebug script (fps modem 1;wait10;fps modem 0). is here anything else what is unakceptable for KZ but allowed on HNS? sorry for huge offtopic and i know this is no place for it. but this community is really old and more professional than any other jumping community so i want help from veterans. iam new on HNS and iam only good in block jumps so i wanna tweak my config and start learning those crazy trollings and shit :)

edit\\ i really want to have smooth game with no position delays what so ever to be able jump people on heads and stuff. for example i really wanna learn that trick that you will make leader dropp jump from head of CT under you. but it was impossible as you saw on that screens coz he could killed me on the ladder from that epic distance
