As I've told you, and others, on here, a few times, charts, there are none so blind as those that WON'T see.
I don't think I need to remind you, charts, after all the meetings, trials races etc, you've been to, how many t shirts, stopwatches etc etc you've gone through, but you're arguing with someone that tells YOU, that saluki/coursing bred dogs, especially his, WILL leave the fastest non ped whippets over 150 yards, which is what he originally said, before he started moving those ever expanding goalposts, in the country, at that said distance.
