This has been proven by two independent studies.

N = 2 isn't data.
You are wrong. Silly wrong. Try looking in the last decade, not the last century. I rarely get less than 5,000 miles from a chain and often 10,000+ miles and that is only at 0.4% wear.

I use Sram Force 22 on road bike. 38600 km at the 4th chain and I shall probably switch to a new 5th chain at 45000 km. It means more than 10000 km per chain. I use to remove, deeply clean with diesel fuel and lube the chain, at every 1000-1500 km. I use a Rohloff caliper and change the chain well before "0.1mm" on caliper, because there is also a lateral wear of the chain that makes shifting somehow hesitating - I shift excessively and sometimes under load. Looking at the chain rings and cassette shape, I would say they will last furter 38000 km - over 70000 km in total.
Chain wear at 100 miles is too small to be measured. Either the chain was not new, or the caliper / measurement is wrong.

Chains are not shipped with the same lube in 2022 as in 1992. They did no testing back then. Friction Facts also did a study but it might be hard to find.
Age and miles have nothing to do with you saying removal of factory lube is silly. Not only does it cost more watts, it causes more wear sooner.

I strip the factory lube off so I can start with my home made paraffin based liquid lube that will be used for the life of the chain. It yields excellent chain life and doesn't attract dirt. Not all chains show a lot of elongation as they wear. Campy chains and the new sram axs chains can be extremely worn at the rollers and side clearance between the links, with little elongation. Measuring the roller spacing between the outer plates on two adjacent links can show extreme wear, with little elongation. Users think it's great to get 6,000 miles or more from a chain, until they install a new chain and get new-chain skip, meaning the cassette is worn out. I have a length of scrap tape measure with a permanent pin through the 10 inch mark that allows for full length measurement of elongation.
I alternate the use of at least 4 chains on each cassette so I'll never get new-chain skip. I'm alternating 10 chains on my two axs bikes.

It's a standard shipping film.
They use smiliar on a lot of automotive parts, truck parts, construction equipment parts, parts for a cruise ship, especially when manufactured from countries with high seasonal humidity.

FWIW, Here's Lennard Zinn from March of this year: Technical FAQ: Should you leave the factory lube on a new chain?

Why would the factory use a preservative on something that is not stored for any length of time? If you wipe off the LUBE on the outside of the chain it will not attract sand and boulders as you claim.

The parts you refer to indeed coated for shipping as in industry we store them in a warehouses for what can be extended periods of time and there lubrication needs are met when put in service, this is not the case with the high quality chains of Shimano, Campagnolo, Sram, KMC who have a vested interest in your finding value in their chains and so use high quality lubes and recommend you do not remove it. I suspect this is not the case with many "budget" chains offered today.

^^^ There ya go. I use wax.......on my windows so I can open them. Would never use wax on a chain.
Usually I use what I got.... more important to wipe the excess off the chain.
