I am wondering why nobody seems to use ROI as an indicator for a capper.
Win-percentage doesn't tell anything about the odds so 100W-20L isn't necessarily any good if the odds is very low.
Units is also very diffuse because some touts use 1-10 units and others use 100-2500 units so +14,2 units might be a lot better than +2680 units.
ROI is a simple way to show how you are performing when you take the odds into calculation. Good cappers will have a ROI around 103-110% and a couple of touts I follow (not from USA) have a ROI of about 120% but they are not recommending play from big leagues like NBA, NFL ect.
