see, you only put the pure AP of the machines it can produce, not the other stuff it can do, so if you want to use that point......just include the feats the Computer has instead, it would be better for your point
Piccolo isn't human tho, and since this is toei continuity, it would have the DNA of other beings since, iirc, Goku also fought Demons and other beings after the defeat of the Red Ribbon Arc
Like, it is still impressive it took this long, but alongside it not being only Goku's Skill to analyse, since it would have everyone else's as well, it would also need to analyse how to properly fuse all these different DNA's, mix their powers, and making it an anatomy that would allow the inherent abilities of them all to be usable for cell, all while also implementing the evolution function he has to make himself "perfect"
all this to say is, in your wording you are implying that Goku's skill in fighting in specific is why it took so long to complete cell.....but that is likely not the case, at least, i didn't see a statement about it, Goku was 1 part of a very big and complex project, unless we have a statement saying that he was the reason it took this long, giving him all the credit is not very accurate
