Quote from the wiki, when it says fuel. Does it mean the two pieces of charcoal placed into the crucible?
Because... do people really use hundreds of pieces of good Q charcoal to fuel their crucibles for a couple bits of good steel?
From my understanding (research courteous of Gunnar), the softcap for steel is (CrucibleQ + CharcoalQ + FuelQ)/3. This means for high quality production, you need to make sure that if your fuel quality is lacking, your charcoal quality and crucible quality make up for it. The larger factions usually would end up using just below top quality trees for their fuel, as to just make it above the softcap.
These numbers however have not truly been solidified since of the length of time it takes to do tests of these things, but Gunnar said he got close. Try having a search around his posts (his old account, his new account).
Also, redid that portion of the Bar of Steel page of the wiki.
