Since we have a history of arguing semantics over content I would prefer to clearly define the terms "Planned" and "Spontaneous" before getting into what percentage of each action is one or the other.


 To me, "Planned" means to "decide and arrange in advance, or prior".

 To me, "Spontaneous" specific to human decision making means "performed or occurring as a result of a sudden inner impulse or inclination and without premeditation or external stimulus".

 Specific to the two examples you provide and only those examples with the exception of all other examples I would consider the "end product" to be "Planned".  "End product" to me, means the intended detonation of an explosive, but not the success of it, just the intention.

 This is specific to the intent of a successful explosive or incendiary device with the exclusion of all other actions.

After all, not knowing to the fullest degree of accuracy, about the particular subject at hand.

My response will be not a definitive answer to a subjective question which the matter needs to be  resolved first.
So my answer is, not responding to a question, which is not the answer, to the definitive answer.

Now, to further clarify, it is my duty to inform all of you that my opinion, is not a opinion, that is gathered from not, relying on the impute from others on their opinion, which may be or not be correct.

So to conclude, a opinion may be, or may not be, the negative of a opinion, which could be a positive opinion, unless it does not agree with my opinion.
