I saw a video somewhere explaining the 4,000 rpms max suggestion. The goal of the Run In period for Porsche is to avoid heat spikes of the internal metals during the early life of the powertrain. Some metals expand more rapidly than others. Porsche determined that at 4,000 rpms or below you could not heat spike your engine. So it is not an absolute, just a place where they can put in the manual to assure you of no heat spike. It was explained that such heat spike could lead to premature wear over the very long run. So my take away is avoid driving that causes heat spikes, such as scaling mountain roads, or idling on the tarmac in 110 degrees, or performing a launch of the vehicle.
Same thing on the mileage - they figure you will encounter enough heat cycles at the suggested 1,850 miles. But it is not absolute. If you did a cross country trip and only stopped for fuel, you may only experience less than 6 heat cycles. Whereas, if you did a bunch of 1/2 hour trips, but only covered 500 miles, you may have twice as many heat cycles.

I like money too, but at some point in your life you realize that just because you bought the T-shirt doesn't mean you really had the experience!
My current Spyder is not exception, my SA wants me to take care of it (which I do) and keep the mileage down (which I don't), for me the ownership experience has to be complete...

The theory behind the recommendations...

Whoa! 4000 rpms?! It is literally hard to keep RPM's under 4,000. I mean, you just touch the accelerator from a standing start and within one second you're at 4000 or 5000 rpms. You go to pass someone the highway and with just a little gas it downshifts quickly and is at 5000+ rpm. In sport mode the car doesn't even upshift at 4000 rpms.
I guess I should give it my grandmother to drive for the first 1000 miles.
