Anyone who just says "it is so because I say so" is likely to be taken with a pinch of salt, I agree. Someone who says "it is this way and here's some non-proprietary info by way of proof" is more likely to be taken seriously.
Anyone who can put together a cogent argument in support of their position shouldn't have to prove anything else. It's up to others to bring counter argument. Just saying "I don't believe you, la la la" is no more defensible than is "it is so because I say so".
In all of my posts (that aren't in the ying yang threads anyway
) I try to explain my thoughts and why I hold a position. It is then for others to argue their position in a similar manner. I'm not involved with motorsport at all although I have a friend who has been at a high technical level in F1. Where I have brought forward info that I've gleaned from chats with him then I have mentioned the source in that general way. Am I going to give his name insupport of my position? No I am not because it would be deeply unfair on him. If others wish to discount that information then that is up to them. I shall lose no sleep over it.
If you are more fortunate than others, build a larger table not a taller fence.
