Fudge - followup

So I now know where the fudge went wrong, at least some of the reasons:

• It should boil for about 30 minutes - not 2 (my case)
• Add the flavoring afterwards, not initially
  
• Allow to cool afterwards before pouring out
• Stir after it has cooled
• Heat slowly
• Place in fridge for a long time afterwards
• The thermometer should not be resting on the bottom of the pan
  

How many mistakes can one make in a single batch ?

Update on cycle accident - The bike is fixed and fit for use. No more head-aches since Wednesday although I am still in almost constant neck and shoulder pain. Tomorrow is my "no park day" so I have no choice but to ride - I wonder if there will be more snow, like today.
