I didn't realize at first that what we were discussing wasn't interesting.

Oh it could probably be interesting, I just don't understand what point you're trying to make. If you're claiming that by using FA or TA (that is, no insider trading nor theft) it's possible for a trader to outperform chance then feel free to support that viewpoint with data.
If you don't claim that, if your point is that the only way to beat the market is to cheat, then I fully agree with you.
No, there are information propagation and price reaction delays in any market. I just gave an extreme example that I fear is much more common than we'd like to believe.
I guess my point then is that your data set is probably biased heavily in favour of traders that don't have informational edges.
