User blog comment:Legionwrex/I figured out how many Reapers there are!/@comment-17706546-20160729221919

Nonsense. Firstly, the Leviathan of Dis wasn't 1 billion years old, the Batarians later estimated it was merely 'several million' years old.

Secondly, the cycles do not produce one single Reaper, each space-faring species is used to produce a Reaper. So 1 Reaper does not represent 1 cycle, several Reapers would - if the Reapers had succeeded in carrying their harvest in ME3, there would be a Reaper created from Humans, a Reaper created from Salarians, Asari, Krogan etc... I would have thought this was obvious from ME2's final mission...

You're making an awful lot of assumptions before you reach the "So there you have it..." stage.
