I like the idea of a smaller basket for smaller/shorter cooks.
When you use lump, you need to be careful to pack it into the fire ring carefully. You don't want to leave a lot of space between chunks. If you just pour it in, it won't hold as much, and you'll get a lot shorter burn. I think with more space for air to circulate, that would shorten overall burn time also.
And yes, wind and cold will make it burn through more fuel faster also.
I do like the idea of using a smaller basket for short cooks though
