Wow! I was wondering what impact it has at all. Using the neutron highway always brushes some stuff off your FSD and I usually had a repair stop when it came close to 88%. I just wonder what it actually impacts. Any experiences with FSDs on a low %? Is it decreasing fuel efficiency, or jump range, or increasing temperature when charging?
I did not really wanted to field test this on my long trip for the CCC but a commander out there might have some experiences with a damaged FSD in a lower percentage range.
My FSD failed once when I was attempting boost in a neutron star. I had not been watching the FSD condition after a lot of neutron star jumps and it suddenly came up with the message "FSD failure", and then as I exited the neutron star vortex, "FSD online", so I may have had a lucky escape. When I checked, it was down to 75% ! It took 1000 units from my Auto Repair Unit to bring it back to full health, and from now on I tend to repair it when it reaches 90%.
