Many of us have adopted verbal scales over the years. Some are 4 some 5 some 6. Same guy just different number of stops.
Really depends on how much we have been drinking.
Unless you know and have smoked with the reviewer it's hard to place too much weight on their thoughts and comments regarding a cigar regardless of their scale, 1-999 or good to bad other than the extremes. Which may be the point of the O.P.
There are things that can help folks understand the cigar better to see if they might like to try it based upon words presented.
We all value different things though and so much of the experience is subjective.
The actual cigar has a broad range of considerations that may be important to some and not to others, things like:
Size
Age
Brand
Wrapper
Packaging method
Storage conditions
Flavor profile
Depth of flavors
Evolution of flavors
Nuance
Finish
Draw
Feel
Duration of smoking experience
Relative smoothness/harshness
Volume of smoke
etc.
Then there is the whole variation between boxes and within boxes thing to consider. Have smoked 1492's that were ehh. Doesnt mean they are not one of the top 5 cigars .. for me. But if the reviewer was smoking that one... People smoke cigars differently. For example nose exhale vs not. These differences can yield radically different impressions of the same cigar.
Giving someone one of your top 5 cigars and they, after smokng one, having similar opinion.. now that's cool.
