Then there's the question of potency prescribing. The late Dr P Sankaran wrote a brilliant pamphlet on this, recently reprinted in "The Elements of Homoeopathy", basically showing that according to whichever expert you care to quote, whatever system of prescribing you used, high potencies, low potencies, whateffer, would all get brilliant results. Here's my contribution. Please don't consider it as expert.  I have learned that the Similimum of the Central State, when given in at least 10m potency, gives an almost instant reaction.

I have many cases on video of tearful widows instantly breaking into giggles, and then into unseemly hilarity within 5 - 10 mins after the remedy. There's one case of a widow who was into a new relationship within a month later, much to the despair, and I suspect envy, of the local widow's support group.  And the girl who had been gang raped, and spoke in a flat emotionless monotone. She "had got over it," but was just having thrush, and difficulties with her husband. In fact she had just left him. On the grounds of emotional trauma and dead emotions I gave Pho-ac 10m.
Within 30 seconds she halted in mid-monotone and giggled, looking very startled as she did so. Then into laughter and a quite jolly remainder of the interview. When I stamped her cheque I asked her if she wanted me to stamp her butt, and she misinterpreted this entirely and hilariously. She didn't return so I rang her husband to enquire after her. I was delighted to find she had returned to him.

I have dozens of such cases on video. I make a point of videoing the patient from the start of the interview until about half an hour after the prescription to get the beauty and drama of that first reaction. It has wonderfully impressive educational value.
