docstring: When losing or winning a lead, this method is called to increment each PLS parameter related to the lead
          in won_count (if won) or in lost_count (if lost).
  
          This method is also used when reactivating a mistakenly lost lead (using the decrement argument).
          In this case, the lost count should be de-increment by 1 for each PLS parameter linked ot the lead.
  
          Live increment must be done before writing the new values because we need to know the state change (from and to).
          This would not be an issue for the reach won or reach lost as we just need to increment the frequencies with the
          final state of the lead.
          This issue is when the lead leaves a closed state because once the new values have been writen, we do not know
          what was the previous state that we need to decrement.
          This is why 'is_won' and 'decrement' parameters are used to describe the from / to change of his state.
