I'm having trouble understanding. Each chamber takes 18cc for an 1280,
not 7cc.

When I vacuum filled virgin carts I usually could get up to 6 fills
from a bottle (you have roughly half a carts worth left). Sometimes
you have to be careful with the last fill that it doesn't suck air
when drawing it up.

I don't know if you are suggesting refilling each chamber as it needs
it by pulling cart out, etc. I wouldn't think so, but if you are this
would be false economy as you would have to do a refill using bottom
filling since seal would be broken. And when you bottom fill, the
filter in bottom of cart doesn't get a chance to strain out the big
globs of bad stuff- hence your printhead may clog eventually in that
position.

It could very well be I'm mis-understanding.

Anyway when I went over the math a few times I always came up with 
carts costing about $26 (BOTH k + color) when vacuum filled yourself. 

The biggest chunk was the virgin carts  and the ink. Except for a
dollar or two for misc stuff like paper towels and distilled water for
cleanup, and the rubber balls for plugging top holes, chip replacement
on occasion, etc.

This does not include re-usables like the vacuum fill kit, chip resetters.

The carts from MIS I think were about $54 set then.
