The double painter works slower than it should be

[MoYuYu]

I'm 5 paint level, the double painter should be 3 items/s, but it just gets 2.8 items/s.

I ran into the same thing last night. And another weird thing is, even when I add extra double painters to make up for the slowness and remove the bottleneck, my output is still very slightly less than the input. Ie, when my input belts reliably measure at 8.0, my output belts reliably measure 7.9. It's like that 0.1 is evaporating into nothingness? This doesn't happen with any of the other painters/cutters I've seen so far.

It's minor, so maybe I'm too picky, but damn does it bother me.

Noticed it too
I suppose this happens because double painter produces 2 items at the same moment, but they can come out only one after another, and while one is out, the other one is still in the painter (waiting for empty space on conveyor), the double painter starts working only when it's "output" is empty, I guess it is causing micro-pause between iterations of painter

I hope I make sense and devs will notice this small problem
