Well picked up, Eagle.
Having said that, there are some slight anomalies in the game that are picked up from time to time. Once, using eraser, my friend and I calculated a max cluster of yellows that we thought was impossible. After running the calculation several times and doing many other runs, we concluded that the score MUST'VE included yellow blocks that had just been dropped by eraser, but were outside the cells. I've noted this a few times, now.
