I go by color, if the amber color is getting dark, I change it. I know that many think this is ridiculous, but it is my car and I do as I want when it comes to the oil.
I change oil between 30-50%. I could probably go lower becuase the DIC is a good measurement tool, but with my vette being a DD, I feel better changing it before 30%

Are you asking becasue you are curious or asking because you want to know when you should?
GM developed the algorithms based on the oil specs that were in place in 97 to be safe if you changed your oil as soon as you could after the DIC hit 0%...
The oil in use now has improved properties ...
Me too.. why waste good oil. Read the info on M1 and you will see it can easily go 12,000 miles. It's all about wear and oil contaminant and if the oil stable why change it too early. 99 Nassau Blue
