I am not saying anybody is wrong, just logically, if you do something that has a random outcome, the more times you do the same thing, you have a higher chance of getting what you want. Yesterday, I had like 4-5 PLL skips, 2 being within like 5 solves. I probably solved it over 200 times yesterday. I timed about 100, and know I did a bunch more solves.
You may not be saying anybody is wrong, but we are saying you are... and there are numbers to prove it. I'm still really struggling to even understand your argument of doing the same thing over and over. Take your marble analogy, it is not at all like a cube. If you have 10,000 marbles, one of which is red, and you pull one randomly out the chances are 1/10,000 that you pick red. But with a cube, you don't keep pulling one out, increasing your chances. You put the marble back in and try again, every time with a 1/10,000 chance. The marble thing wasn't even the same as me trying to argue the CO+PLL skip.
