Thank you for clarifying the issue, I must admit it was very confusing. As a side note, still, at least with the One Call type offering I do feel there is a mismatch with the description. The data I get back with a free call has an 8 day daily forecast (setting the count parameter to 16 does not change anything, btw) and examining the min and max values - they do closely match the day/morn values provided by the api as well, see below. So I would argue there is a way to get daily min/max values with a free api.
