They were probably safeguards/margins in case some terminals did not work. In any case, no one promised 6 ports. I expect to be able to upgrade Saturn to Jupiter, but not further.
AHEM! This photo is what they describe as their controller board and you see 1 2 3 4 5 6https://www.kncminer.com/news/news-39
I am more worried about those capacitors. Everything else seems like nitpicking.
I have the six ports BUT only 4 DC/DC converters on the ASIC boards.
When did KnC start using only 4 ?
