As I said in another thread. They just need to fix how the cap is done. Currently they are using a % based cap, so that the maximum coins the boss actually outputs is 100mil. (1 mil per %). It's the easy way for the programmers to do it. However, if you look at the damage you do per round, it will show you the return you are actually SUPPOSED to get, if the programmers weren't so lazy. The way it should be programmed is by a hard cap that caps at 100mil, regardless of the damage you do, and you should accumulate coins based on what is shown in the per round return. The fact that the two don't add up, is proof that this is a bug, and poorly programmed. They just need to program the cap properly.
