I am not questioning their drain interval recommendations. But I'm just not comfortable going more than 3 track days on the same fill. If it were not for the track days I would certainly go 7-8K.
I'm much more concerned about trace metals and their trends. I am looking for any preliminary findings that could indicate motor issues. My first motor blew up at 87K with Mobil1 3w30. Do any input is appreciated.

Reasonable enough decision. 5k miles even with 3 track days, yet the numbers show it held up to that well. I'd say you could up your cap to 5 track days or 8k miles. This oil didn't shear at all to the track use.
What are the track days like? What is the service seen? Hours and hours of high-speed driving or what? Some specifics there might help.
You might could consider a K&N oil filter for kicks. Supposed to be a racers filter.
Didn't seem to hurt using stock filters. Just making fun.
Nice report. Couldn't tell you tracked it at all. Good report for a Corvette too.
The 5K is mostly freeway cruising to work. But plenty of spirited driving on the streets. A track day consists of 2 hours of high RPM and oil temps averaging 250*
