Re: Argument with a friend over ROI
Technically since he invested nothing, any positive outcome would be an overall infinite return on investment. However ROI is simply a statistic that we use to measure success/failure/profitability in SNG's. Simply saying that it is infinity doesn't help him understand how well he is doing. Also, it is rather standard that we refer to ROI as the average ROI of each SNG combined rather than an overall return on initial investment.
