Anthony b sanders’ use of the term YoY is up 70% YoY because it is easier to say YoY than to say more than last year. Also to make it seem like he has more credibility YoY than last year.
True, it is easier to say YoY (Year-over-year) than to repeatedly say “since the same month last year.” I dropped him a line and suggested he explain YoY at the beginning.
