Here is my answer! In fact, I have still not known the TS Forecast's meaning. 😄

I came up with slightly different answer because of how I imputed the sales volumes.  I first filled in the missing weeks data using monthly averages.  Then I averaged annual data to get the monthly total for May 2013.  It's a small difference (153 vs 149) but looking at sales (Units), the 153 seems more in line with overall sales trends.
