You are correct. I think they are at their very best at this stage when the skin is mostly yellow with just a blush of green remaining, the flesh is still pale green and they are bursting with juice. Is "blush of green" an oxymoron? I dunno. But at that stage, they are more juicy but still lime-y. When the skin gets all the way yellow, and the flesh starts to fade towards yellow, they become less tart and lime-y. At some point after they get really yellow, some of the pith that runs down the center can start to turn brown and they aren't as good with some bitterness creeping in. That's all my 2 cents 
- I have one lime tree and am no expert!
