Exactly! So what happens when you blur every 3 pixels? Do you end up with 120 or 40?

Get the point; the fact is, those three pixels are not fixed; I mean, we could have 2+1/2 red, 3+1/3 yellow, 2+2/3 red and so on... right? Then, that it works good or not I think is dependant also from each disc.

Yep, it definitely depends on how the disc was encoded. It can't kill certain rainbows in the JSC, for instance. The chroma bandwidth is really, really wide on that one and it dips into the lower frequencies.
