=== Manufacturing XP ===
Also, the ability to make XP in a particular skill depends what level you are. If you just started with manufacturing, you have to make your XP with fur scarfs, later you can do leather helmets.

  1 fox fur + 1 thread = 1 scarf
  
  Market cost of 1 fox fur: 8gc
  
  NPC cost of 1 thread: 2gc
  Mixing time: 1,75 sec = 1,75 gc
  Selling them (45 sec run for selling 180 fox scarfs): 0,25 gc
  
  Sell price of a scarf (NPC): 10gc
  
So, assuming no fails, we have 2gc deficit for 12 XP (base experience) - quite good. The problem is that fox furs are not that often offered in the market in bulk.

If we cannot go for fux furs, lets make leather helmets (I assumed a walk from VOTD store to Trik, carrying the ings for 100 helmets):

  3 leather + 4 thread = 1 helmet
  
  cost for 3 leather: 14 gc
  cost for 4 thread: 8 gc
  time to walk to Trik, mix and sell: 3,2 sec = 3,2 gc
  included cost for food: 1,8 gc
  
  critical failure rate 5% (at manufacturing level 39)
  
  average revenue (selling to Trik): 19 gc

So we spend 8 gc per helmet for 45 XP (base experience) which makes 5,6 XP/gc, roughly the same as with fox furs.

Let's try the manufacturing school in WS as an alternative:

  cost for 3 leather: 14 gc
  cost for 4 thread: 8 gc
  time to walk to School and mix: 4 sec = 4 gc
  included cost for food: 1,8 gc
  
  total cost: 27,8 gc

Assuming again a 5% critical failure rate, we get 90*0,95 base experience for 27,8 gc (135*0,95 XP on Day of Schools) which makes 3 XP/gc and 4,5 XP/gc on Day of Schools, respectively - still below the value of making business with Trik.
