.....Showing your stance as indefensible. .....
Ok then, let's see how firm the foundations of your position are.
Your argument is that this sentence:
2. They have had a reasonable amount of time to arrive at and determine the lie; and,
gives you permission to not start the 30 second timer until you have had time, and you don't specify how much time, until you've had time to choose your shot and choose your disc.
So in the scenario where you throw your shot into the edge of some trees and you don't know whether the disc has got a clear view of the basket or whether it's tucked in behind a tree, you don't know whether there is low canopy in your way or not, tell me, how are you going to choose your disc and how are you going to choose your shot without.......um......what's the phrase.......er.......you know......without arriving at and determining your lie?
In this scenario, how can you be there, working out what disc you want to throw, and working out what line at the basket you have, without being deemed to have arrived? And without being deemed to have determined your lie?
Is your argument that arriving means specifically stepping on to the lie? If it is then that seems like an obtuse reading of 'arrive'. If the rules meant that, wouldn't they say that? When I pull up at my mum's house and text my partner that 'I have arrived', am I lying because I'm still in the car on the road outside her house and not actually inside the front door?
The only time you are going to be able to choose what disc you want to throw and choose what line you want to throw BEFORE you have physically arrived at your disc is in the trivial circumstance where you can see where the disc is, and what line you have, pretty much from the get-go, which removes the need to allow people to choose their disc and shot before the excessive time clock starts in the first place.
Your interpretation of the excessive time rule only has any value to a player if they can choose their disc and choose their shot after they have seen where the disc is. For a large amount of shots that means actually physically being at the disc.
You my friend.... have arrived.
