The different length of NPD tracking periods is why the metric "average weekly sales" is commonly used to gauge momentum.
For example, May sales are 200k and June sales are 210k. On the surface it looks like June was the better month, but when the metric "average weekly sales" is applied, you get 50k/week in Many and 42k/week in June, so it was really May that had the better momentum.

This.
And if I'm not wrong, Switch would be gaining momentum:
Jan - ~270k - 5w - 54k per week
Feb - ~280k - 4w - 70k per week

if you look at it that way its gaining momentum, but consoles sales usually see a 70/80% increase in Feb compared to jan.
