  My slightly modified & explainified

  Shulgin Scale:

Technically it follows three so four is not wrong, in that you are unlikely to encounter a +++* (+4) below the full +3 effects of a (psychedelic) drug,

+++* (+4) is a rare case where the effect of the compound only serves as one (pre-requisite) piece of what allows access to such states. 

The heterogeneous fourth symbol being a glyptoglossic reminder that it is 

not a four category system

of +1 through +4. 

With a bonus sixth category +++*, (+4), to record a special state sometimes encountered where the effects of the drug seem to….yeah. 

And it is wise that once one has acquired at least two of something (be it white powders, or +++* experiences, anything really) it’s prudent to create a label.
