Maybe new enquiries ki waje se dip huwa hoga. It will come back and with proper utilisation of CC, keeping CUR low will definitely increase Credit Score.
I don't think CUR of Loan is considered.
I have a Personal Loan and the Score was constantly 747 till February when I applied for Credit Cards and score went to 723 and I got Cred Card in March then it kept increasing with low CUR. Currently, it is 763.
