Love it. I don't know why that one eluded me. "Modest" feels a bit closer to the low-end than "middle-ish, but it got me where I wanted to go. I really wanted to avoid using anything like "amount", "degree", measure", etc. Cheking thesaurus results for "modest", I think I'll settle on a slight restructuring with "moderate". "Judicious" could be good too with a slight restructuring, but it feels a bit on the higher-end for my purposes.
