Agreed, the important part about being concise is not that you can boil down a complex idea into a short statement, but that you can give the questioner the information relevant to them. When there is too much relevant information to be concise, that is in itself a relevant (and concise) answer, the art is giving the questioner just enough information to ask another question. Personally I find doing that sort of thing _extremely_ difficult, and doing it in real-time as part of a verbal conversation orders of magnitude more so.
