Hi, I'm happy to contact you here. I'm the editor (authorized according to the contract) of the Chinese version of this book. The number 1167 on Figure 4-4 and Figure 4-6 should be 1670? I wonder how 1167 comes from since it says it is 10X growth rate. I will submit other questions later. Thank you for your patience. I hope we could provide more accurate info to Chinese readers.

In figure 3-9, the 4164 on the very left should be "16,667"?

Please let me know so we could provide the correct graph to our readers.

Thank you very much！

The original sentence is For SaaS products, according to various industry benchmarks, 2–10% sign up, 15–50% become subscribers, and 20–40% churn on the first pay period. That’s a 0.6–1.2% customer conversion rate.

We caculate the customer conversion rate, the minimus should be 2% × 15% × 60% = 0.18%
the maximum should be 10% × 50% × 80% = 4%
So it should be 0.18%-4% customer conversion rate.
We are not sure how the number in the book come from.
I'm still the editor of the Chinese version of the book.
Please let me know if the recalculations are right. Thank you for your patience.
