It should have been 75% from the off like previous CGs. Those at the top get paid more and have bragging rights of being in the Top 10 or 10%.
To fly out there and help with the Community Goal is reflected in the credits you earn. The FSD is the icing on the cake just like protecting an engineer accused of terrorism in return for a heat seeker missile. That overwhelmingly went in the Federation's favour regardless of moral standing. She was probably guilty but a free module overlooked that issue.
That CG was one of the busiest I've seen.
So many Commanders have so many credits now that the CGs sometimes get overlooked as there are little rewards other than credits. Even explorers have stated how gutted they are to miss out on the newer goodies to be earned in CGs now as they're so far out in the black.
The CGs are definitely better when there something to be gained for all your time and efforts. Just showing up is not an incentive.
In this case, I believe FDev should reluctantly give out the FSD to all that signed up for the CG this time.
In future, be consistent and clear on what level triggers the reward as we don't want to see incentive taken away by lowering the bar to low, that CGs don't get to Tier 5 or even end.
I suggest a 50% level to receive the bonus reward, that is easily achievable for Commanders to aim for and maintain for the duration of the CG.
I also suggest permit locking the CG system to stop Fleet Carriers jamming up the Nav Panel and causing persistent lagging. Maybe allow a handful of them that have Services available to ALL to allow players to refuel, repair and restock, so they can get back into the CG quicker.
