I think this really depends on what your background is and what your personal expansion of "understand" is. Assuming a cold start (which would never actually be case), with your approach it would take seven years to get through eg. Assembly, C, Java, Haskell, Prolog, Factor and and J. Obviously you would have a better understanding of each paradigm and their strengths, weaknesses and tradeoffs after seven years of study than someone who tries to get through all seven in 2017. But that person will have a much better understanding of all seven paradigms in one year, whereas you will have no basis to compare the single language you've learned in that year to anything else.
