You’re welcome, Gene! No worries about the names. As for the number clarification, I apologize for any confusion on that front!
According to the B/R Stylebook: “Nounal height-related constructions like '7-footer' are also presented in digits, except when they appear at the beginning of a sentence (Ex. 2: the talented 7-footer).” So, in general, numbers under 10 are still written out and 10 and over use digits. This is just one of those exceptions that was recently clarified for us.
Please let me know if any of that isn’t clear/if you have any questions. Thanks!
