odd issues

Hey,

something's been bothering me so I've come here.

I get a hand history like this far too often.

If you'll notice the amount of duplicate rank hands dealt.

each line is one hand.

So how many times were you expecting? There are only 13 ranks. Also see this:

After I posted that I continued the table.

later on was dealt 6 consecutive hands with a Q,
then it stopped for a couple of hands,
then was dealt 5 consecutive hands with an A.

several hands after that I received four of a kind J.




As of this moment, I'm on my 15th back to back duplicate ranked hands,
meaning I'm receiving the same ranks twice, this number would be much higher if I were to add in the number of 1 hand in between.

This is out of 5498 hands.

It would be easier to respond if you showed evidence of what you mean by "15 back to back duplicate ranked hands."
Are you saying that 15 times in a row you got two hands with the same ranks right after one another?

Randomness means that that there should not be any systematic pattern in the results observed...which would result in Predictability of the next outcome(s).

A lot of research shows that Humans believe that they are detecting patterns when none in fact exist.
When you have repeated sampling over and over and over again, you are going to see what appear to be "streaks."

We see it at the Roulette table and Baccarat table, where people are convinced that a Streak of Black is happening, for example, or a streak of Bank winning, when these are just random artifacts.

I have seen 22 Blacks in a row one night, followed by 17 Reds a few spins later....

Anybody playing the "Bet on same as last spin" system would have made a nice score.

But, it was simply a random fluctuation.
The wheels are scrupulously maintained to avoid anybody discovering a biased wheel and profiting...

if the wheel kept producing long strings over and over again, then somebody should be very worried or very rich.

IF you sit and watch random events long enough, you will see every possible outcome and apparent "pattern."

As Kent suggested, you should figure out what the expected outcome of any two ranks being dealt twice in a row...
I doubt that it is all that rare....

I sat at a Blackjack table and saw everyplayer dealt an Ace, including the dealer.

Shocking...but with 7 decks times 4 aces = 28, it is not that rare to have Aces in 6 hands.
You are going to see all sorts of "rare" events...the question is how you interpret them.

You need a long period of testing before concluding that any Bias is occurring....certainly more than 5,000 hands.

Here is an article that talks about how often you can expect to see certain combinations:

However, please do keep posting if you think you truly do see something you should not be seeing.
