Well, your ".{25}\s{3}" portion only gets you to one space short
of your 29.9, so your "(\d+..." fails to match " 29.9" because
there's an extra space there. My guess (from only one datum, so
this could be /way/ off base) would be that you mean "\s{4}" or
possibly "\s{3,4}"
It seems like a very overconstrained regexp, but it might be just
what you need to isolate the single line (or class of line)
amongst the chaff of thousand others of similar form.
