can you post the question? i’d be tempted to say that with 4% change in style that htere is the appearance of a style drift but not conclusive yet. I’d look for anything that is 7% or 8"% or more before claiming style drift. Maybe even as low as 5%, but 4% is the grey area for me. why did i choose those percentages (5% or higher)? I have no idea…they seem material to me compared to the lower percentages…hows this for a crappy response.
I believe others have also expressed their frustration on this. The %changes are such that it can be interpreted either way depending on how you are feeling that day
I remember the question asking “significant” change. But I have to check.
