rush/anti rush

[wizard]

It seems to me that poker often runs in streaks with a monster rush where every hand hits at one end and super pockets that can't ever win at the other. Most of the time you are somewhere in between when you play good starters in appropriate position but you will hit most of the flops that you see or miss most of the flops. It is agreed that cards break even over the long run but I believe that they are streaky in the short. A good player recognizes this and slows down when things are poor and speeds up when they are not but how do you know when the streaks are changing? Has anyone ever studied this phenom?
