User blog comment:SlumDragon/Event Drops, Poi.Statistics and You/@comment-26486243-20160229025145

The last point is amusing, because the wikia formations are word for word copies from poi-statistics for the most part (since so far, it has never contradicted any of the information listed in our enemy comp threads, we're quite sure it's 100% correct), with exceptional cases where wikia users uploaded their own API serving as a second source that confirms them. If you follow the citations I left in each formation you'll notice it links back to poi.

Still, because poi IS the source of the wikia formations, you can't say the poi formations are correct because wikia says so; if poi had a bug and had an error, the wikia formations would replicate that bug.

The other issue is that for conditional drops like: If Fleet.Ships.Prinz Eugen.exists? Drop rate = 0 Else Drop rate = x End The result will be that the value tracked by poi is an underestimate of x, because of all the Admirals who farmed that node and couldn't, by definition, have any chance of dropping Eugen as the existence condition is true. The poi values are accurate only for unconditional drops, and represent only the lowest possible value for conditional drops.
