no you seem to be unable to read my posts properly. nowhere on this thread have I referred to the impact of weight relative to price, race outcome, punting success, etc..
my initial comment was in response to someone saying that 5kgs of extra weight wouldn't slow a horse down - I commented that the laws of physics mean that it should. that's all that I've said, you seem to be reading other stuff into this
however I will defer to your superior intelligence, which you continue to seek to demonstrate (in a painfully sanctimonious fashion) and I will concede that you know more than every trainer (and handicapper) in the world who think that weight does make a difference
