I'll try to update this with the new formula when 3.1 hits, but I'm now a mother, so there's much, much less time to play, which means less time to collect data myself. If people could post their desynth level (BEFORE the desynth), their exact chance of success, any bonuses (tinker's calm, bacon broth, melded materia), the name of the item (and rlvl if you know it), and the exp gained (optional), I'll recreate the formulas and explain what's changed in the guide.

So, a template:
- dSkill:
- Item: (r#)
- Success: (Careful: , Melds: )
- Exp:
- Items:
