How do you validate a betting system?

Using the simpler DRI:
R22 wagered, R3.08 profit = ROI: 14%
12(/22) winning bets

DRI = 12 * (14 / 100) = 1.68 (well below the recommended 25 for confidence)

Hermit I think the DRI method is seriously flawed. Think about it. If you took one bet on an odds on favourite at 1/1 and it won, that formulae would validate your system even though you only had one bet. I believe the maths on that would be... roi=100% and one bet so therefore 100x1=100 points which is well above the 25 point cutoff.

The universe doesn't promote any systems, I don't want to burst any bubbles here and if a system works for you then fantastic! This discussion was brought to the fore long ago and heated battles transpired between EINSTIEN and BOHR and modern mechanics reached the most mind baffling conclusions using the famous QUANTUM LEAP. I would be here all day if I went into the details but the moral of the story is that EINSTIEN was stubborn and was supprisingly incorrect as well. You see EINSTIEN believed through physics certainty could be predicted whereas BOHR argued that certainty can only be concluded through observation... as EINSTIEN said, he likes to think that the moon is there even when we not looking at it.

The theory of PROBABILITY would arise from the very same onservations BOHR made back then, casinos and bookmakers alike use this theory with exquisite accuracy and they dont need to predict what number will come up next on the Roulette wheel or which horse will win a race, over time with enough spins and races they will WIN, that is the only certainty, lol.

So gents, certainty cannot be predicted but it can be observed, the rest is all mumble jumble, there are no systems, if you want a system google KLOG and witness a theory which describes entropy and the movement of everything from order to disorder, that's where we all end up as punters.
