If you were right, and even a low estimate of 10% of the people experiencing it comes here to post about it, you'd have a TON more people complaining about it. That alone proves that you are one of the 1 in a million cases.
Personally, I've raised armormech, armstech and cybertech to the 350-370 range and artifice to about 260 or so, and while raising them I REd everything I made. I have had very few cases of getting less then 2 successfull REs out of the 10 items I make in each bracket of 20 (1-21, 21-41 etc etc), and quite a few cases of getting 3-4, including several cases of getting all 3 blue items from a single set of 5 greens. The same has held true when I've just REd stuff that I want/need without leveling from making the items,
...And then I've also had to try 20 times before I got the first blue earpiece.
It's all down to luck, and when there are millions of streaks every day (assuming the above claim of 1 million players is correct - I haven't checked), these things WILL happen.
It is possible to change to code to adjust future chances based on past results (Sid mentioned in a presentation that they did that for at least one of the Civ games) so that extreme cases like this doesn't happen, but just because BW hasn't done that, that doesn't mean the percentages given are wrong - rather the opposite, making that change would cause the percentage to be off.
