[All Platforms][Spotify for Artists] Artist Listenership Data and Graph Reports Incorrect

[yahudansawoke]

Have difficulty understanding the maths that Spotify uses for summation and reporting of Listernership over a 28 period on the Artist page

The daily numbers are listed below. These daily listeners sum to 274 for 28 days, averages at 9.7 per day, but Spotify reports total 28-day number as 86; can anyone explain the maths used ?
