Maximizing Blueprints?

I haven't tested a solid week of doing large only, then a solid week of doing small only, to compare which completes the tasks faster.

But i've always assumed they work out evenly. I'd like to know if this has been confirmed.

But when i choose large, it seems i'm not tasking the characters as frequently. it seems to require more cycling of the metal in between the glass and plastic, leaving those characters doing nothing.

i guess it doesn't matter enough to think about it. the last two times i had 4 days to spare. and that was while doing the olympics stuff too.
