So from the guides posted, these are the numbers for hours in barracks:
v1.0 3 debuffs - 891.56h (238.17 + 653.39)
v1.0 2 debuffs - 714.62h (225.48 + 489.14)
v2.0 2 debuffs - 730.37h (335.19 + 395.18)
Ive an average of 4 different guides for each of these adventures, so i think those are the numbers from the guides posted
The huge difference from 3 to 2 debuffs on v1 is so big because on the 2D guides theres alot more nukes, some of those are my 'evil runs'
Some ore numbers:
With 2 debuffs we get 585 extra ore after the whole chain, on premium
The whole chain on prem drops a total of 2224 ore for 2 debuffs, plus around 250 from the excelsior while spinning
