Hmm, that's an interesting hypothesis...and should be easily testable if anyone wants to record data for expedition 1 or 20 with just the required ships (sparkled) :P

If that's true though, I don't think it applies to drum expeditions (in the same way, at least) because their GS rate (with the appropriate number of drums equipped) stays at around ~99.9% as long as you have 4 sparkled ships, no matter which position the sparkled ships are in (I personally don't sparkle the FS and 6th ship), whereas the GS rate falls if you only use 3 sparkled ships, even if one of them is the FS. (AFAIK)

Anyway, here's what I have so far for 4 sparkled ships:
