Do not know and do not care, Just think it as shorter bias, extra care like You were playing against online casino. If you can avoid it choose another table. I play mostly roulette, single Zero, Closest thing to random, no way of orquestation. Still longer straight and zz runs. Once on the run I stay on until it ends. You must always pick the easiest way to win that you can. I only give up to the casino the house edge, anything else no fu.. way.
