My numbers don't include recyclers because I saw no clear way to keep them fed. While it takes more EU I'm not concerned because the net gain is still huge.
Also I calculated needing less EU without recyclers but that doesn't make any sense. The last time someone said they had different fusion numbers I ended up being wrong. I threw that spreadsheet together hastily last night so I'll have to take another look at my calculations and do some testing.
Also my mass fab EU numbers were based off of this page:

Replication EU numbers were based off of NEI. Can anyone confirm that they are correct? They're listed in the facts tab of that spreadsheet.
