Hello,
thanks for your interest and feedback in the new hitpoint system! I'll try to answer some of the questions for you:
Yes, it does - LC stands for "Left or Central" - for cases the individual plane has only one of these controls instead of two.
The released plane with hitpoints is still in a way work in progress. Armor and damage values will be tweaked, it's not even its final form! When releasing hitpoints on Wipeout, its main purpose was to show to community how it will be done, so there's something to look forward to and prepare their mods, and we didn't do this fine tuning of the values yet. However, it's on the list!
Those are hitpoints for the lights :) Not explicitly defined in the config like the rest. However, try to shoot the light, you'll see it's getting the damage.
Thanks a lot for your suggestions and feedback! It is indeed very valuable to us, and we'll do what we can about it. I'll happily look into it, however, you're right that we'll need to fit it in the timeframe before the release and the list is already quite long :)
