There is nothing accidental in this world!

Each ad has a coefficient of the hits in the display cicle, which is calculated after each display of this ad. Coefficient of the hits depends on the weight and the number of ad impressions for the ad. All ads in the queue are sorted by this coefficient. The ad with the lowest coefficient is in the top of the queue and is the first candidate for the show. If this coefficient is the same for two or more ads , preference is given to the ad with the smallest ID (a unique identifier).

When the display cicle is finished coefficients for all ads are set to zero.

When the coefficient of an ad reaches the 1 value, this ad is excluded from queue.

Thats all.

Ad Slider for SAM Pro addon. You can purchase it on the CodeCanyon.

All right, so it should be.
1. You have 2 ads for the same place. You use this Place twice on the same page. When the first instance of Place queries the current ad it gets the first ad from the queue. When the second instance makes a request of current ad, it will receive a second ad from the queue, because the first ad has already been shown and another ads are no in queue. And so each time you restart the page.
2. Each object Place is a virtual representation of the physical space on the site page. From this it follows that the repeated use of the same instance of object Place on the same page does not provide a plugin concept and therefore is not welcome.

Does this ad contain function document.write?

Do you really have the Place with ID 6?
