When I was mixing multi flavour mixes then they would likely include a couple of flavours from each of the three categories in the chart, then some fruit or booze flavour. While if I was mixing a single flavour it would come from the centre or right hand side.
I never categorised the flavours exactly like the chart but it fits with my experience. The right hand ones to me taste nothing like baccy, the middle one smell a bit like baccy in a pouch but not like smoked baccy. The left hand ones were a bit like smoking and were an important background for me. Never found a flavour that tasted like a smoked cigarette (no bad thing for me) but cuban cigar and Havana flavours did relate back to the smoking experience..
