The basic keys to avoid bad batches (I found out by making bad batches) are:

• Avoid contamination... get sulphite into it asap, keep everything hospital-clean.
  -Keep primary fermentation temps low, like 12-15 deg. celcius
  
  I didn't use any splenda, so mine is very dry, pretty tart... but no vinegar or off-flavors....
  
  Honestly, I didn't even check the spec. gravity when I racked... But I think cleanliness and temps are way more important than most other factors.
