I think this is pointless, unless you journalize specific maps, ones like where the big bosses are or where you can great rare items. Or else what would be a point of a journal, people only want to know the stats for drops of rare items not your everyday journal. But i like your idea, IMO i think it be better if you posted up the stat of lets say week then i think it would be a really nice chart. Anyways these are my suggestions and opionions please don't take it too seriously.
