This year's baseline for the Switch is 40.338 up 5,8% from 38.126 while PS4 baseline is 14011, -27,97% compared to last year's 17.930

The PS4 this week is -38 units compared the same week last year. A flat yty week

Update: Charts corrected

Ca you remind me the method to calculate this "baseline" ? I am a statistician in the automotive industry for 30% of my activity, so I was curious about this and I finaly decide to ask what is this thing.

Hi! Sure thing. Other user helped me with the method. It seems to be more accurate. Here are the steps:

1. Medium of all the weeks so far. Eg: the medium for the Switch in 2019 so far is 52.850

2. I get again the medium but only of the values that are lower than the "general medium" of number 1. Eg: There are 13 weeks that are lower than 52.850; using those values the new medium is 40.338

Hope it is clear, and if you have a better and more accurate method we can use, happy to know about it.
