Why do you own 3 PHBs?
I only own 2 physical copies. One english (first day), already glued together and a German one I was gifted by a friend who got a free copy for proof reading the translation. After it was published. Not a proof reading version. That was a secret she could not tell me while she was doing it.
And a 50% discounted online version from the essential's kit. Or maybe a full price one and I gifted the discount to some friend? Hmmh.
So I also own 3 copies...
So... back to the actual topic:
If only 55% of PHB owners buy the book, it counts as a massive success. Since the original 2014 PHB has sold like hot potatoes for the last 10 years, 55% of the current PHB owners means more copies sold than 2014 initially. I guess if just 10% of the 2014 PHB owners buy a copy initially, it would count as a massive success. And then we can expect the 2024 book to boost the sales for the next 10 years, while we could have expected the 2014 books to drop in sales.
