While I do believe in bad run or good run, which is often connected with short term luck, I do believe in long term luck (or unluck) in poker does not exist, so the word "continous" here... gets "NO" from me.
I believe, when we have bad run, it influences our mental shape, the quality of our play, so we can suffer it longer we "should". But see, in such case it is no "luck" anymore (even if it could be in a beginning), we just play worse. The same with a good run, just opposite - when we have a good run, we usually just play better.
