i thought of something like this ....it would be a 12 hour mirror of the time you choose though i if chose 1pm - 3 pm capture time there would also be a open window at 1am-3am capture time as well....but to offset the more open windows for ports there would be a cool down time for it to be recaptured..... one more thing is make ports linked to where you could only capture a port adjacent to the one next to it.
