What is the highest UC GPA?

Yesterday, I went to the college counselor to check my weighted UC GPA and was told it was 4.5; however, I thought it was capped at 4.4 because there are only 8 semesters of AP classes counted. Please clarify what the maximum UC weighted GPA is. Does ELC affect whether or not the GPA is capped (I read this may be the case on an old post).

Thanks in advance for your help.
