I do not understand your second question, but as to the first, the god of statistics can treat you right because he counts the number of trades that you entered with that sytem.

When you roll the dice, your chance to suffer three losses in a row is much higher when you roll them 30 times, than when you roll them only 3 times. Same for trading. I have no reference link, but can find an introduction book to statistics in the links page of the manual.
