I need some help from anyone that might have gone through this before.

I got a 7 years for fraud and money laundering and served 3 1/2. I beleive that im considered low risk and never had any problems with police before or after my sentence. Now I'm out on license for 8 months. I used to see my PO once a month, and not in the COVID-19 area, I was told I had only to call me once a month. Which is fine for now.
I asked my PO last time, if after so many months, were my appointments going to be less frequent, like once in a couple of months/ three months. 

He said that once a month is the minimum frequency that there is. This once a month reporting to PO will remain for the rest of my licence (providing my behaviour doesn't change for worse, which I don't think it will).
I told him that I know other guys living in different areas, and they are seeing their POs less frequent, even with similar situations like mine.
He told me that once a month is a national policy and anything else is not true. 
I was just wandering if anyone else thinks the same or what my PO is saying is not entirely true. I am aware that the POs could not always be op to date with the latest regulation. 

If what the PO is saying is not true, can I please be pointed to the source of information so I can counter argue him. 

Many thanks in advance.
