I am not super familiar with other top men but don’t they always have 4 or less planned quads. From what I saw even juniors are doing harder layout than some of the top men.
With the reduced time, less 1 jump, harsher penalty for falls, it needs different strategy. Oh ya, now only the last 3 jumps get 10% bonus, only 1 quad can be repeated.

Shoma, the OG &World silver medalist, landed 4 quads but with flaws.

Click on 'judges scores' . Yuzuru landed 2 quads, fell on 1, poped the 4th quad.
Boyang Jin, the OG 4th place finisher, attempted a 4 Loop at a competition in China, new jump for him. Not sure if Boyang plans 4 or 5 quads cos he didnt manage to land even 3 quads in that competition.

Mikhal Kolyada, the 2018 Worlds bronze medalist. Landed 1 quad, fell on 1, not sure if he was planning a 3rd quad. He looks like to have ditched the 4 Lutz, which he was famous for falling during OG season.
Yuzuru, Shoma & Kolyada won the challanger events despite the mistakes and falls.
Javier, the OG bronze medalist is not mentioned cos he is in semi retirement/retirement after Olympics
So, Nathan needs to work out with his coach what is the layout he can realistically perform which will obtain the max pts. By WC 2019 that is, where his role as the main US mens single is more crucial.
