New Server, Rates Help Needed!

[Drocona]

well sv_maxupdaterate is just how much updates your server will allow to be send, this is however limited by the tickrate, tickrate 33 will send 33 updates per second, but when you decide to run 101 tickrate it will do 101, so that maxupdaterate value is always good.

sv_minupdaterate should keep the updates above 20 per sec, to avoid lag. when updates drop below 20/s the server starts to shock a little.

sv_minrate is to keep a steady and good data flow to the clients, so they won't lag out.

formula which I use:
bandwidth*128/players

also, how many players are you hosting?
another also, connections have overhead, which means unusable bandwidth, this is roughly 10% of total bandwidth given by the provider.
