Say i calculated my Standard Deviation to be 30.7 for the last 8 sessions i played in 2/4. Yes i know this is a EXTREMELY small sample but what can i conclude from this??

Does this mean i make +-$30.7/hr?

Also, what is a good standard deviation? (Smaller better i presume) but how small is good? I know these are silly general questions, but this sort of mathematics is interesting to me.
