Up to you if you still want to persevere with his 'education' charts. BUT, I really do think it will be fruitless. ?
He's been convinced, or someone else has put into his head, that saluki/coursing breds are the only dogs that can catch hares.
And, as a few people on here have said, myself included, if you want a dog that will catch a hare after being dragged around several acres, for 4, 5 or 6 minutes, before it makes a catch, SHAME, that hare has been outstaminered, and nothing else. May as well get a couple of beagles or harriers.
