I guess that's a fair point. Sorry for oversimplified explanation. So, to attempt to improve on your further clarification: technically it is $75b per night created and destroyed each morning. And 3 separate cycles of $30b will be created for 2 weeks and then destroyed. Therefore $90b injected for 2-weeks then destroyed. Point is this is being injected to help banks cover their overnight exposures with the hope that they won't need the help anymore after Oct 10.
