95% confidence level , accuracy is not possible it is about how likely it is to not be a random coincidence, with 95% confidence it is accepted that it is unlikely to be random . remember 50% confidence is coin tossing . Therefore a lot of tests are needed no fewer than 10 if you toss a coin 3 times you can get a 2/1 result easily that does not mean that heads are 66% likely if you toss 100 times you are close to the theoretical 50% again Results required for a 95% confidence level: (95% confidence level is commonly considered statistically significant) Number of trials vs Minimum number correct 10 - 9 11 - 9 12 - 10 13 - 10 14 - 11 15 - 12 16 - 12 17 - 13 18 - 13 19 - 14 20 - 15 21 - 15 22 - 16 23 - 16 24 - 17 25 - 18 9/10=0.9 18/25=0.72 So the needed correct results are lower the more tests you score . If it is not a true abx other factors can creep in (it can anyway ). Therefore I like triodes approach it is similar to a meta research In science if you have for example 8 studies of something and 5 say yes and 3 say no, you do a study where you evaluate the combined results for all studies to get a better confidence level . If triode for example collects 100 responses to his abx app and if a bunch of them are not properly conducted or done exactly right it may not matter that much -- Mnyb -------------------------------------------------------------------- Main hifi: Touch + CIA PS +MeridianG68J MeridianHD621 MeridianG98DH 2 x MeridianDSP5200 MeridianDSP5200HC 2 xMeridianDSP3100 +Rel Stadium 3 sub.
