11/65 for 5*. I did the daily Fleet plus 3x50 and 3x100 energy refreshes every day of the chase. First day I wasted all 3 50-crystal refreshes on normal nodes forgetting that hard nodes had higher %.
Pretty pleased with it. It's the first Galactic Chase I actually attempted to unlock.
For the record I did any hard node with a ship that I don't have 7* for 8 attempts, and then any ship that I already had 7* so I could convert additionals to pricier shard shop currency.
Nodes:
Poe X-Wing
Gauntlet
Sun Fac
Umbaran
Then I usually burned any residual energy on the TIE Advanced node.
