The odds on not getting a gold+ are around 48%, so the odds of this happening are a little under 23%


The odds of 2 gold+, little over 12.5%
3 I think is about 2.6%
4 is about 0.13%

...I think so yeh the odds of that happening are only 2x the odds of getting 2 golds in one pull

Thing is other then the high end whale ships I figure you could get by on event girls alone - and I suspect if you bloomed max ampied and dedicate to the event girls perhaps the whale ships too...
