When you wonder if the Lumeris super duper behemoth module is as useless as it seems, you go and test it!

TL:DR 

• system has behemoth for +250% trade value in orbit, system in scanner view does not include this bonus in "other sources" of extra trade value,
• empiric observation of the value converted from hero skill (which is trash btw) on system reveals no real difference.
• The commercial branch can not be used on Juggernauts negating it's other bonuses close to completely (behemoth locked to 1 lane strategies)lumerisBehemoth.sav

Since there is no real system trading value number showing to follow I shall illustrate a difference of having the behemoth with Lumeris-specific behemoth mod available from juggernaught tech utilizing the useless "ULTIMATE" skill of the Lumeris hero family, which converts 40% of dust from trade route to food and industry showing 15,1. which means the value of the system is about 30ish for simplicity. Of course this is just an attempt at understanding the trade value, cause yet again, I point out there is no actual value to track.

With +250% behemoth in orbit (as the trade value of the system is 30)

without +250% (behemoth flies away! also there is no difference, also checked next turn if recalc happens, no difference)

can you please redirect me to a thread where this debuging stuff is explained?

So I can stop myself from posting.
And is it the skill that is not working as intended then?

It's modding tool. Well explained at here: https://github.com/Scrivener07/Endless-Studio/wiki/ES2-Modding-Tools

Lumeris hero final skill is actually 40% increased F/I output from passing trade routes, which is not affected by SSTV.
