I had eight zeros in the marque today. This things happen and are not at all any special, give it time and you will see all combinations. It is about 20 numbers in the marque, and it is the same occurrence of any series of 20. If it was sure we never saw them, the wheel should be biased.
It is sometimes hard to understand that 20 seven in a row is possible, it is very unlikely, but it is as unlikely as any 20 numbers will show. Try to find a marque at BV which show up 20 the same number and order 2 times, it is likely you must wait hundreds of years.
Some patterns have more meaning to a human brain than other, they are still very rare every
time you look at the marque.
I have posted somewhere here a screenshot of 9 coming 4 times in a row, and one gap an other 9. I think Stepkevh said in one post then he played a repeater system he got 11 of 20 in 100 spins.
