WINHunter has a processor for High/average/low numbers. It also has a processor which calculates the pair high/average/low numbers. Hmmm, maybe I need to ask what you mean by high/low. To WINHunter, high/low is how many times a number has hit in a given time frame. The same holds true for the Pair high/lows. You can combine the functionality of both processors in one filter, or in seperate filters. Here is how it works.
An individual processor (let's use a high/avg/low processor here) is told by the parent filter how many drawings from the history to use, and how many to skip. It is also told by the filter when to process, and when not to process (useful for cycling and for triggering.) This means that you are not stuck with a single filter setting (i.e. 16 previous drawings.) You could essentially configure 2 filters (or more) the first one would look at the Highs for the past 8 draws, and the other filter would look at the lows for the past 30 draws, oe whatever you might think of. You are not limited in how to configure the filters/processors. What you have to keep in mind though, is that the partent filter controls what portion of the history that the processor will look process. Also, when doing parallel processing, you also have to remember that the output scores of filters are combined into a single group (that is why WINHunter shows them under a group in the tree display), and then the group score is passed on to the selector, which actually is where the selection method is applied.
Maybe that will tease you enough to get you more interested in WINHunter *wink*.
