Eeeeesh

5.8 eh??
That's a big difference. Okay. Thank you

as another direct test,

7x T1 Extractors + COM == 15 per tick
3x Land Facs, each producing a LAB w/ Adjacency == 13.5 per tick

I should be -gaining- mass, but instead it's showing a loss of 4 per tick. -4 is on the display, and my bar is shrinking.

from the desire to be quite thorough, let me describe the math:

What should be: 5/tick for a LAB, building 3, with adjacency should do this,
(5*.9) + (5*.9) + (5*.9) = 13.5
( 4.5 ) + ( 4.5 ) + ( 4.5 ) = 13.5

apologies, it's not 12 but 13.5, so rounded up should display -14 on the bar right, as it uses only whole numbers?

I'm seeing -16 on my mass per tick, quite literally 16 mass per tick is being taken from the pool.

This is where I'm having the disconnect.

my mass bar is -16 when building 3 LABs. how does this adhere to the math you're describing please.

even setting up experiments, where my mass should be positive, i'm seeing mass TAKEN - when it should be at least fractionally positive.

so, by trying to get adjacency using 3 land factories each bumping up against 1 extractor, in my attempt to get LESS mass cost per tick I'm actually using MORE mass to build these units?

my mass bar, the FINAL result, shows I am losing mass when I shouldn't be...
rounding doesn't quite cover what I'm seeing.

building 3 LAB's costs 16/tick... WITH adjacency, which is MORE than what they'd be if I had -no- adjacency.

I'm so confused on this, this is a bug right? or is it that the game is... intentionally flawed?

I am working on my early game, and find that when I hover over the Land Fac building a Mantis it shows -3, but my Resource Bar shows a -4 despite being adjacent.
I test this between all Fac's, and have found even wilder results when producing 3 L.A.B.'s, i see -16 mass when without adjacency they'd be -15... but with they *should be -12.

please help me understand.

Some have mentioned a 'rounding' effect, but the mass pool itself is being affected quite actually in accordance to the +/- that it's displaying.

Kinda confused, thank you for you help!
