Change Based on oil used---

Mobil 1 or Castrol Syntec Edge at 15K
Amsoil at 25K

I DD 50 miles, use to be 105 a day.

SC for 38K miles with a 25 row Oil Cooler. 56K on car right now.

NO Problems, I drive the car hard each day. 5-7 PSI of boost 2 to 5 times each way.

No WOT longer than 3-5 seconds in 2nd/3rd gear, any longer would be to extreme on the street.

I do not track. When I did SCCA would change after 3 events, 20 years ago, not in the Z!

Note: Castrol Syntec Edge, I got some on my hands and it took 3 days to get it off. Same weekend I also did Mobil 1 in my wife's car and it washed right off.

I just did an oil analysis with Blackstone Labs and at 5,000 miles the tech said I could extend to 7,000 on 5w30 royal purple. I do have a z1 25 row oil cooler so I'm sure that contributes to longer oil life.

Nissan's OCIs are very conservative for modern lubes. If not worried about the warranty, 5k (or longer in some cases) will work great for most DDs. If you drive hard and/or live in a hot climate, you might want to go with more frequent changes, but modern lubes are pretty damn tough.

If you're that OCD about it, Jar's UOA suggestion is the way to go. Overkill for a DD (unless you suspect abnormal wear, eg, an older, high-milage engine), IMNSHO, but if you helps you sleep at night, why not?
