It's fine. Just expect that some members may think you are padding so you can get extra karma points. Ignore them if they say anything. 

Hi valR:  Personally, I try to answer a question as thoroughly as I can with the first response, even if I am contradicting myself when giving a second scenario.  I am one of those who is not prone to thumbing up a second answer, especially when it could be made as a comment in response to someone else's answer.  If I want to say something else, I might edit my answer; it isn't reread by people, I'm sure, so it's not the ideal answer.

I think if you have a solid answer to post, certainly.  Everyone's opinion and insight is welcome, even if we don't all agree.  I look forward to your perspective and usually find myself nodding in agreement.  Usually  :D

If the question appears, it is there to be answered.  There shouldn't be so many repeats but if you like the first answer, by all means, write it again!
