Booted up the mod in a creative world to see how easy it is, and noticed a few things:
All fluid recipe's seem to only output 1 fluid, eg: 1100 crude oil to 1 petroleum (A little too high perhaps)
This also seems to be the same for some uranium recipes and all science packs too, though perhaps the science is actually intentional?
Quite a few building recipes give 5 or even 1 item where I would expect 10, eg: Steam engines, beacons, rocket silo etc. This includes satellites and all modules too.
And lastly, the rocket silo is using 0 power, despite saying it's max consumption is 26MW (Beaconed) (This is no idle draw too)

The fluid one is especially bad, as one yellow science bottle now requires 13 billion units of oil.
Which for 1 per second, is almost 1 billion refineries running basic oil processing, which alone uses 2.5 petawatts of power. Even 1 per hour would require a quarter million refineries.

I do however, find these large numbers very funny.

I've been testing it in freeplay, and obviously that's been really slow so I didn't catch these later-game issues. Good idea to test in creative!

I know the reasons for these issues, but not too sure the best way to get around them. It has to do with stack sizes (assembly machines can't output more than an item's stack size). I guess for fluids the "stack size" is just 1. Maybe I should just disable recipe modification for items where the stack size is too small altogether.

I'm not sure the case with the science packs, actually, since they should have large enough stack size. I also don't know why the rocket silo wasn't using energy. The way I do the energy increase might make it take 156W now that I think about it, rather than in the MW range. Was it using any energy?

And yes, the numbers are funny XD
