This scales poorly unfortunately.
Depending on strain and ambient temperature, I've seen as little as 4f above ambient when fermenting ales in the low 60s, and as much as 14f above ambient in one fateful batch I tried to run at 72f ambient with dry yeast.
Fact is, the width of the possible range really means you need a stick-on thermometer for your vessel (a buck well spent). And the temps in the instructions reflect what that stick-on thermometer should read.
