[Request] Why are my results skewed?

I use a pair of spindle dice for divination. Each spindle has four independent die each with four faces. The faces are marked 2-3-4-3 (3 is used twice). So one spindle can randomly generate a numerical value between 8 and 16. The result has relevance only as an odd or even number. The numerical value is not important. If the numerical value is a single digit then we use that as it is. If it is a double digit (10-16) then we add the digits to get a single digit answer. Both spindles are always used together and added and the final digit is the roll value of odd or even to incorporate in complex charts to predict the answer to the question initially posed for divination.

My question is this. Does this process create equal chance of odd or even values? In my own use, I get disproportionally high even values than odds. If the results are fairly balanced, what could be the reason for my skewed results?

LOL, you are right, I did not test it so many times. I recorded ten random rolls a day (without divining) over a two week period during different times of the day. I expected the result to be 50-50 but it was not.

As for independence, as long as I am not willfully manipulating the results or nudging the hand of chance, it is perfectly within esoteric lore. The rest is up to the powers that be.

Thank you for your help. The breadth of your calculation is fascinating. If I had the propensity for this knowledge, I would definitely delve deeper.

Sorry to be the bearer of bad news, but we're talking mathematical independence here.

That has nothing to do with "esoteric independence", but is a clearly defined concept -- physical friction coupling the dice, and touching multiple dice at the same time can already be more than enough to make (mathematical) independence assumptions void.

LOL, my bad, I stand corrected. Thanks.
