Max delayed pairs - US Powerball

RC (Chronological Delay): Indicates how many draws ago a number (or combination of numbers) was last drawn. If a number has a chronological delay of 34, it means it has not appeared in the last 34 draws.

RR (Relative Delay): Indicates for how many draws a number, combination or series has held the top position in the delay ranking. For example, if the number 03 has a chronological delay of 20 draws and is the most delayed in the lottery, the relative delay indicates for how many draws it has been at the top of the ranking. If the previous leader was just drawn and 03 has just risen to first place, the relative delay is 0.
