SRAM Force AXS 1x12. New Chain Sizing?

Road Cycling ďIt is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.Ē -- Ernest Hemingway

SRAM Force AXS 1x12. New Chain Sizing?

2021 Specialized Tarmac Pro w/SRAM Force AXS 1x12. SRAM Force AXS 12sp w/flattop cain, Love it.
Time for a new chain. Need some advice on what the best method for sizing a chain is for this setup. On my prior SHIMANO 105 Groupset I would use the "Big-Big and add 2' method. Im reading some differing methods and opinions as it relates to SRAM Force, and im a bit confused.
Really appreciate any help. Thank you.

SRAM has documentation for this and you should follow it. Itís still the large large plus two method with suspension bottomed out.

Box published an alternative method for 1x that used the longest chain to make tension in top gear with the suspension topped out. It ensures youíll have enough chain for the RDís biggest rated cassette. But itís only for 1x derailleurs where the top pulley shares the axle with the cage pivot, and the method above is more conventional

Or if you are just replacing a chain, just make the new one the same length as the old.
