Using numerical difference instead of proportional difference is illogical.
By that logic a console that sold 95m compared to an average of 100m would be a bigger anomaly than a console selling 0.1m compared to an average of 5m.
Whereas selling just 0.1m compared to your usual 5m is clearly an anomaly, while selling 95m compared to your average of 100m is basically normal.
As illogical as removing Virtua Boy because it was a dud.
