[La scatola magica]

so I found this in some of those server configs you can spot being posted here and there

sv_stats 1 sv_unlagsamples 1.5 sv_maxunlag 1.0 sv_unlag 0.5

and basically i wanna know if those values the guy put there make any sense at all (like sv_unlag 0.5 wtf y use 0.5) and whats the exact meaning of those cvars

also ive been wondering lately does the "fps_max" on the server side have any use at all?

thanks in advance
cheers
