well for one that site's data is off. claims DOGE confirmation time is ~30mins. click through to the chart. shows confirmation times hovering around 1 minute. reward per block shown ~40k. way off. each block currently rewards 250k: visit http://dogechain.info/chain/DogeCoin and subtract subsequent outstanding amounts. 250k difference. those are just the ones i noticed immediately, i'm sure other data is wrong there too.
