January :
Tool : NS : 1.0 ; PS4 : 0.76 ; XBO : 0.10
NPD : NS : 1.0 ; PS4 : 0.69 ; XBO : 0.36
Good month again ! XBO sharp drop was detected but overestimated. This is not a surprise as when a product get out of the charts often, it is mechanically undertracked due to 0 point being lower from the truth... We need top500s... lol
