Best TTT CFG Settings?

Curious... what is the most optimal TTT cfg settings to have?

CFG settings for..

sv_minrate

sv_maxrate

sv_maxupdaterate

sv_maxcmdrate

decalfrequency

Reason I ask is because I've been having random ping spikes and I'm starting to think it's a cfg setting that's out of wack. My cfg for all of those is..

decalfrequency 60

sv_maxrate 0

sv_minrate 100000

sv_maxupdaterate 99

sv_maxcmdrate 99
