We have been speaking to Google about the problem and there are many many aspects that they take into consideration when they decide what results to show to the individual viewing the results. CPC bid, click thru ratio, viewer location, viewer history, time of day, repetition count, number of items within a subaccount, how many times items from the subaccount have been shown already and many more.
It is not an exact science and we cannot guarantee you will personally see the results you wish for each time as every single user is different in Google's eyes.
We will keep working on things to fine tune the best we can as time progresses.
