Just posting my opinion quickly too, as I've only played a around 8 rounds with these settings.
/pxiserver 0 and /pxiclient 0 seems to be very nice, and I finally don't feel like I get hit from seeks when they are still pretty far from me.
We tried the settings with pretty high values too (Iforgot the exact values, the match was on scrapyard with sj and kev I think - in case it was recorded), and that way the game certainly felt like when you have 300-500 or so ms ping.
There was an instance of kevin not dying on elm super (dying but respawning instantly on the same spot*), it was recorded too.

Good job, I like the update!
