In homeopathy, one should not claim that he or she is right in his/her decision in prescribing a medicine to a patient. That is why, every homeopath have different point of view on one patient case.
A book in india is very famous "PRINCIPAL OF PRESCRIBING" by Mathur. He has presented the complete picture of prescribing in his preface. Please read preface completely you will find all answers of your questions.
Your question reminding me a discussion in the past on this BB. No rule in homeopathy for prescribing. No body could claim perfect prescribing method.
All methods are the need of today's time.
