It's pretty silly really. If the customer want 80/20 and the customer pay extra for this service, I am sure there is no reason that openreach can provided you fttc service for up to 80/20 product if the line had a max of above 60Meg or more. But if the max rate below 50Meg then I see there is no point to have faster 80/20.
My parents line was estimates at 60-80Mb and her line go live at 71Mb with max rate of 74Mb but since the year went, her line suffered crosstalk went down to 48Mb. So, her maximum rate is 49Mb so, my parents have decide to save their cost, downgraded to 40/2 with plusnet later this month. Funny is BTW checker still saying her estimates line rate is between (see below) as it proved BTW checker isn't correct due to crosstalk with her line max rate current sit at 49Mb not between 60 and 80Mb:
