Should the presented points by different referees within the LoRs be convergent or divergent?
With due attention to the applied consulting with some experienced faculty members my final conclusion is that a mixture of the convergence and the divergence better be taken into account within the LoRs.

In other words, the investigator of the LoR is not eager to read all repetitive points about the applicant within the different LoRs, neither be distracted by the bombardment of the many non-overlapping points from different referees, will which not lead a coherent imagination from the applicant.
