How did you survive the break-in period??

I think it's safe to say that much of the discussions and theories on what's proper break in and potential adverse effects of improper break in is just speculation as no one has yet to publish any objective studies comparing cars that are broken in properly and cars that are broken in hard and compared the power and longevity of each group of cars over 5+ years and 10K, 50K, 100K+ miles. Or did the same comparisons then had the engines torn down and measured for excessive engine wear, abnormal tolerances, etc.
I don't think even the people who actually designed these motors know whether a car that is redlined starting at 500 miles is worse off than a car that is redlined begining after 1000 miles or 1800 miles because none of them have conducted any objective comparison tests themselves. If these tests exists, I would appreciate if someone can share the results.

Likely because despite all the thousands of collective hours spent arguing about this, it likely doesn't matter all that much. Rings will still seal even with a soft break-in and the potential differences would likely fall under what is measurable in a dyno on a street car.
So at the end of the day, spend your 1800 miles tortured by your self imposed 4k rpm restriction while others enjoy their car. 1800 miles is probably the average yearly miles for a lot of 911s, so its sad that many owners will go a year without getting to truly enjoy their cars.

Each to their own, but there isn't any real downside in doing the break-in properly, to your point about the duration and enjoyment, for me, i would say waiting for the allocation/shipment/delivery/PPF jail which took all up 11 months of waiting for me, was way more painful than having the car and doing break-in properly for say 11 months.

Some of you should never buy used.
You will not sleep well not knowing if the break-in protocols were followed or not...
Beer sounds like a good idea.

I can only speak for CDN market. Aside from Porsche recommended mileage at 3000 km. Both Porsche genius at my local dealership on delivery date and my SA recommended first 1500 km to keep at <4000 RPM. Both times they told me that without asking.
Personally I did a hybrid of 1500 km and increased RPMs by 500 every 250 km, kinda like the AP suggested method. After about 2250 km, I let her rip. No ragrets! 😛

Exxon Valdez Captain - An iceberg cannot puncture my hull.
British Petroleum Deep Water Horizon Manager - We don't need a blow out preventer!
Boeing software engineer - Our software alone can never make our 737 Max stall and crash!
VW and Porsche - We would never cheat on our emissions tests!

The best engine break-in video I have seen. Sixteen minutes long. Mentioned above.

I've watched this before. A lot of good points

Yeah agree 100% and a big news flash for the break-in Karens, chances that the used 911 you bought or are considering was "broken-in" strictly by the absurd 1,875 mile suggestion is is extremely low verging on zero.

It's not really relevant to break-in, except that misinformation is rampant in both cases.
