depth of exprinace is a factor eg yesterday I wrote a feature extraction tool in 2/3 of a day (including geting up to speed with python) to strip out the usable body copy for a large uk website. I could do this so quickly becase I had 3 years previously spent several days experimenting with new scientist's archive and allready knew what library would work.
