How it works
When a character participates in one of the types of projects listed above, they progress its development by a certain percentage. Each successive attempt on the same project has its efficiency reduced by 2-3%, meaning that a single character is unable to finish most of the projects single-handedly, as their efficiency will eventually drop down to 0%.
If another person contributes, all other participants' efficiency is reset to full. Thus, the most efficient way to participate in a research/project/PILGRED repair is for two or more characters, preferably with Skills beneficial to the work in question, to alternate working on it. This will guarantee that their and/or special skill points like , etc. are spent as efficiently as possible.
Note that NERON Participation allows NERON to advance its projects every cycle: this does not count as or need relaying.
NERON's only friend: Having this skill in the crew means that NERON project progress will always be the highest available percentage, rather than a random amount from withing the range. This means that, for example, a project where you'd usually have a base efficiency of 13-17% etc. will have a base efficiency of 17-17%. Efficiency still degrades with participation as usual, however.
