You're relying on a single set of computations to tell the user to change their oil without knowing what kind of oil is even being used.
The Maintenance minder was DESIGNED around the ability of the recommended oil. If you use full synthetic then you just have extra security.

The MM should use numerous computations and they are much more accurate than the ignorant 3k changes. What the 3k miles was on a car in a very cold climate with all short trips less than 5 miles? What if the 3k was in a car driven in the very hot Arizona desert at wide open throttle all the time?

Where as the MM will take into count:
  • engine load average
  • hours of run time
  • average RPM
  • fuel consumption
  • perhaps peak engine temps and average engine temps

The system will generally tell you to change your oil at around ~5,000 miles, but depending on the oil you use, it could last a lot longer than that.
The maintance minder in my wifes Benz goes beyond 10k. Many german cars go 20-30k on one oil change.

The manual states that there's a special break in oil. It's really nothing more than Honda factory oil mixed with an additive that makes it look extremely dark.
Then that would be "special"! Can you buy the break in oil at a parts store, NO. I don't think you can even order the breakin in oil.
