Sometimes figuring out what a person is trying to get across, be it question or advice, is difficult. I admit, Fiver, Ian and others have left me scratching my bald old head more than a few times. It sort of clicks after a while, usually, but there is always some wondering going on. Getting those wheels turning is only half the problem, it's getting them headed down the right road that is the issue many times. Having to think in nano-seconds over a fraction of an inch make it even tougher. But, hey! That's what makes this interesting. Like I said the other day, if there was one simple answer, like Bhn, we'd all be shooting 30+Bhn and we'd have no problems! It's not like we can't make 'em, they just aren't the whole answer!
