This is my first spot meter so please forgive my ignorance. What is the sub-scripted number value next to the F-Stop value (below, and to the right)?

Sekonic L-478D with subscript f-stop

I've read through the manual over and over, and it really isn't clear.

    This seems like an exact duplicate of the other question, even if its title is not very obvious — and the implication is that the, accepted answer to the other question is wrong. – mattdm Mar 25 '17 at 2:51

The subscripted number is showing the measured value in ¹⁄₁₀ -stop increments above displayed F-number. So for instance, in the manual when it shows 5.67, it is telling you that it measured ⁷⁄₁₀ stop above f/5.6, which comes out to approximately f/7.1 (5.6 * (√2).7 ≈ 7.14).
