The point values are probably as good of an approximation as any, but I think the retailers need a weight based on average revenue generated for gaming. I would imagine that Amazon and Walmart count a lot more than Best Buy for instance. Gamestop may be pretty high on the list as well. I think Target would be the least impacting. This might clarify more on the Xbox/Switch ordering.
Oh, I totally agree, and that is the plan, I am just saying I will wait for first NPD data before trying to "weight" retailers. And when the time comes, I'll be happy to have suggestions.
You can totally start trying to adjust the formula right away though :)
