Sorry, I'm a stats nerd!

The "A Dollar A Day Takes the Pounds Away" Jan 24-Feb 20 game has been finalized! It had 40 winners for a pot that 67 people contributed to. That's a 59.70% win rate. The gross win per person was $36.23 each. Meaning the net win per person was $8.23. 

I wonder what the average win rate is?
