How to give crafting machines a default productivity bonus

[RhyniD]

I've been looking for a few hours, but all I got was a lousy bonus_progress and module_effects

So I'm trying to give crafting machines (assembly machines, electric furnace, chemical plants and some more bob mods stuff) a default productivity bonus.
For example: an assembly machine 1 has 5% productivity bonus, an assembly machine 2 has a default 10% productivity bonus, etc.

Anyone know how to accomplish this?

There's no system in the game to do that.

It's also exploitable.

How about adding a productivity limit to factories? Just like how there is a limit to the max efficiency. Would that be possible to mod?

I had to try it. Just for the make-work. Thanks Dave. Oh, and your video player (Sandstorm) is just insane!
