btw, I uploaded the spreadsheet to an htm.
http://e.sixbit.org/howmanyhands.htm
according to my numbers at $1/2:
hours (PT) 7.38
wr/hr (PT) in $ 12.33
sd/hr (PT) in $ 14.1601
confidence (PT) 0.95
I'm 95% confident that my wr is between $22.54612576/hr and $2.113874238/hr.
That doesn't seem right with such a small sample. Is it?
