I did the math. Assuming you worked 24 hours non-stop to complete your 'day', you would have to type 26 words per minute...each and every minute of those 24 hours, non-stop, no researching - nothing, just pure typing, in order to come up with (75) pages of 500 words per. Cut it in half to 12 hours, that's 52 words per minute...non-stop, around the clock. You may be able to bang out that many characters to complete 75 groups of 500 words, but I dare say you could, with any certainty or professionalism, call them 'articles'.
I stand corrected. I didn't calculate it, I was just going off what I think I can do from past performance.
