Rogerhub Accuracy?

When my counselor calculated my UC gpa, which she claimed is the algorithm the UCs use, it came out lower than what it was when I put it into rogerhub? Is rogerhub even accurate at all for calculating UC gpa?
i am confused. Maybe I input the numbers incorrectly, just to make sure, can someone calculate my UC gpa for me?

Using RogerHub and based on your reported grades, I get a 4.04 UC capped weighted GPA.

I have calculated the UC GPA by hand and using the Rogerhub Calculator and come out with the same value.

That’s what i thought, and this was my eaop counselor too. now ik that she knows nothing. ty though.
