2 mins rest between 4x4 sets seemed fine. Less rest for 3x3 and 2x2 etc.
5 mins rest between each cycle of Campus/Push/Core is enough as well.
Keep track of your hourly point total so you can beat it next time.
At MOST rest up to 2 mins between problems during the "power hour" avoid long water breaks or talking with people. Bouldering isn't supposed to be fun and you know that! :)
