Really? I can lower the cache time to maybe a match length but would prefer to still use the cache due to the performance increase.

I suppose in the worst case at 5 minutes you are 2 matches behind, if we go with a match length the absolute worst you can do is one match behind. Would a 2 minute cache be more acceptable? I may also try making the caching system smarter, obviously for regionals that are already completed the cached version is fine for a lot longer than for regionals that are running at the moment. Either that or take a peek at the cached version (if it exists) and if a match should have occurred (based on the original schedule) discard the cached version... I don't know. I will try to lower that number as much as I can. Who knows, this whole thing could crash and burn 1st week since that is the first time it will really be tested under real load.
