It is an Ace only from Tee pad calling it that, doing a hole in one is if you just keep throwing from a tee. however if the disc gets stuck in a tree in California above 2 meters and the disc somehow falls out into the basket before you get to doing the next throw, say wind or something affects the disc then I would count it unless in a PDGA tournament.
I have had 1 true ace in my life in my first year of mid 2003 to mid 2004, soon after in late 2004 early fall or early 2005 in spring the hole moved the basket and tee pad location for safety, throwing across a road that vehicles are supposed go slower on was not safe as we would see impatient often newer players hit the back of the vehicle, sometimes some players try to play beat the car, and worst the person would throw and the car driver would turn at some nearby spots try to play hit the disc because they are the other people in the state park who hate the small amount of $$$ that gets used for a Disc Golf Course. Not Realizing how much $$$ a course can bring in to a State park for a tournament with the people who play are often camping or in a camper/large van to save time, when other tournaments like Fishing they do not even need to start off from the state park if on a bigger body of water like a lake or even stay in the campsite if they plan to launch from other places, they will stay at other places including often cheaper City camp areas.
