As others have pointed out, the ambient conditions to which the meat is subjected would play an important role in the process and end results.
You must, at all costs, maintain those proper conditions.
And most importantly, and this may be difficult for some, you must resist the urge or temptation to inspect your meat during it's curing process, to not handle your meat, or play with your meat.
Of course, if some strange and tragic incident occurs, such as lightning striking, and if your meat were to catch fire because of that lightning strike or other tragic occurence, than it would be acceptable for you to grab your meat and beat it, but only until the fire is extinguished.
