How does the battle tactic Needs Of The Many work? The description is "+10% crew lost per battle phase on Ships, +50% Crew damage bonus on Ships", and the tooltip states "Sacrifice Manpower to get more power for this battle; use it if your ships have extra Manpower to get a bonus for this battle". Does this mean your ships take more crew damage from anti-crew weapons, or do they lose 10% of their crew each battle phase? Do they do 50% more damage in general, a damage bonus based on the amount of crew they have left, or do they do more crew damage with anti-crew weaponry?

Gossamer's effect is to produce 100% of a system's trade value as influence; is there any way to figure out what a system's trade value is, expressed in a numeral? Everywhere else I see trade value expressed as a percentage.

Third-tier FIDSI luxuries give "+15% X per System Level on System"; does this mean that using them in a Level 4 Modernization and no other modernization levels will add a total of +60% X to the system, or just +15%? E.g. I used Jadonyx for level 2, Redsang and Jadonyx for level 3, and Endless Foundries, Redsang, and Jadonyx for level 4; would the Endless Foundries add a total of +60% Industry because the system is level 4, or just +15% industry because it was only used in a single system development upgrade? Edit: I tested this and if only used In a single system upgrade, a tier 3 FIDSI Luxury will give +60% FIDSI at system level 4. I checked by comparing a single Endless Foundries upgrade on a level 4 system to the Vox Populi boost, which is +30%, and the Endless Foundries boost was exactly double the Vox Populi boost.
