I like the way you wrote this, and I think it makes good intuitive sense.
Minimum length describes the shortest possible chain that physically permits big/big.
Maximum length describes the longest possible that permits the small/small without dragging the chain on itself due to the cage angle. Anything between these two lengths will work well in most cases, though certain optimizations might be possible in certain situations.
Like you, I prefer longer chains to shorter ones.
