I've been doing expeditions 5 and 9 on and off since November 2013, using just 4 sparkled ships (and no other ships, i.e. the minimum requirement), whenever my first expedition fleet isn't spamming expeditions 2 or 21. I've never recorded any exact data on this, but just judging from my memory and experiences, the GS rate does seem to be around 65-70% with 4 sparkled ships on those expeditions. I will record more exact data about these expeditions and get back to you in a month or something.
