Draw Skips are the number of drawings or intervals between draws when the Mega Ball was NOT picked.
You can use the Skips to help you determine how long it normally takes for the Mega Ball to be drawn again.
The following table gives you the last time the Mega Ball was drawn (draws ago) and the Skips or intervals between previous draws. Some numbers appear to go for long Skips before being drawn again. You should examine the Skips to see if it is one of those long Skips or whether the Mega Ball is approaching its high Skip maximum and will likely be drawn.
