By the by, someone has apparently found the odds for the Spyke ordering system. Someone told me the odds on my GameFaqs post. I'll quote the answer.
"If you're level 16+, for a gear that has 3 default slots, the odds are:
- 30 % chance of getting no sub ability (so it's the same as if you ordered from the shop, only the price differs)
- 60 % chance of getting the first sub ability
- 9.5 % chance of getting the first 2 sub abilities
- 0.5 % chance of getting all 3 sub abilities, so an exact copy
according to the Japanese wiki
http://wikiwiki.jp/splatoon2ch/?%A5%AE%A5%A2 . I don't know what is their source, maybe there is an official strategy guide released in Japan.
