HOW LONG DO THE PROGRESS BARS TAKE TO MOVE AHEAD AFTER DOCUMENT SUBMISSION

[d6k5d3]

I submitted all required documents on December 13, 2018. I received the acknowledgement on the 13th itself. Since then there has been only one blue bar above the details of my application. I understand that it's a long process, and there have been holidays in December. However, I am wondering how long the bars usually take to move ahead after submission of documents. My medical is done, also biometrics was done last year.
