I don't think it's valuable anymore. Pre-2020, DLR had a very predictable rhythm that the service was able to analyze and use. Ever since the park capacity, reservation system, and staffing quality/levels have been fluctuating, as well as all of the recent revenge travel/travel demand, it's too much to account for algorithmically.
I had renewed it another year in hopes that it would get better, but I found myself often the only person submitting data on the Lines app, and it was always grossly wrong in its hour-by-hour prediction (whereas before, it was pretty deadly accurate).
