No, there's no offsetting. Let's look at some hypothetical math/orders:
Store A: 50
Store B: 160
Store C: 40
Store D: 300
Store E: 1000
Store F: 250
Store G: 70
Store H: 140
Store I: 20
That should capture a reasonable profile of store sizes. Total copies: 2030. Total 1:100 covers based on orders: 17.
You can see how the 1:100 ratio disconnects due to the smaller orders, and, no, the larger orders are not getting 3 extra copies to offset that.
Right. In your plausible scenario, the count would only be off by 3. That's why I stated that there are *approximately* 2500 copies of the variant, after also factoring in international orders, there are perhaps more. Also, this book was very clearly over ordered so there is a very reasonable chance that many smaller stores ordered more than their usual numbers because of the hype.
No. Not 3. Fifteen percent. So, right there, you can trim the overall number down from the 1:100 ratio by 15%.
And, yes, I tried to skew the numbers to larger, to account for the hype. There are many #1s where smaller operations are probably only ordering 5-20 copies. I figured 20 was probably a rock bottom guess for this book, but I'll check with my LCS, who is in fact a smaller store volume wise.
