My parents (substantial breeders, growers and finishers) have been using Peter and his principles for around 12 years now. They have seen their fertility improve a lot in this time, which is why they became involved in the first place. Their feed conversion has improved and they have been winning paddock-to-plate style competitions. In the beginning I too was skeptical of the principles, they went against most things that I believed beforehand. However, fortunately they persevered with it and have a much more productive herd now.
Peter is one of the most opinionated, arrogant people that I have ever met and that certainly doesn't help him sell his product. The fact that he is VERY ill is another reason that he isn't as active as he used to be and you don't hear his name much. The man has a lot of faults but he sure knows what he is doing. Sure it is strange that he can't tell you exactly what he is looking for and that you're not an expert after attending the bloody expensive course but do you expect to win an NCHA event after attending an Ian Francis clinic?
We have many friends and family that have done the course and use the grading systems themselves as well, it is very expensive to have him do it. There are plenty of people that believe in Supergene but since it is seen as "cultish", nobody is going to come straight out and admit it for fear of being attacked (like you did with rebeef). Unfortunately, it is the same with any forward thinking programs, strangely enough some people see GFP and LSS in the same light! Anyway, it seems that you have all made your minds up but I just wanted to put in my 2 cents worth and give you a bit of food for thought.
I also found it very interesting that none of you haters have actually really been involved with Supergene, just sayin'...
