One of the properties that is important in battle is type, another is level. These are assumptions made by the calculator - we can't know for sure without seeing the game's source code, but it goes on what information is available. Some don't agree with the calculator - for instance some don't think that level is important at all - but personally I think it seems to model the in game rules and behaviour pretty well. So diamond is good against champion because it has type advantage, and a higher level diamond has a greater chance because it has more level advantage. It all depends whether you trust in the calculator and these rules it's built upon. I always use it in battle, and find it useful.
