The problem with having so few bets, Sunchu, is that when the inevitable losing run comes along they can drag on for weeks – if not months. Especially at the odds you’re trading at.
Adequate turnover is also vital to sustain a profitable betting strategy. Obviously anyone having 7 bets per week at an ROI of 20% is going to make more money numerically than someone having just 2 or 3 bets with an identical ROI, despite achieving the same percentage profit margin.
Don’t get me wrong, this is not a criticism, just an observation. I want you to succeed as much as the next person.
But I do know a thing or two when it comes to formulating methodologies. So stick with it, but be flexible, and look for areas that you think you may be able to expand in to.
