Long story short ,
The reasons clones are clones and dont quite line up 1 to 1 is simple...
Its not because of chemists..
Its not because of stupid expensive equipment..
Its not because of the juice being aged in a virgin walrus for 6 years before being blessed by monks upon bottling..
Its simple... We dont hold the actual recipe ..
We are playing with nothing but educated guess work.. But there are so many variables when it comes to flavourings that it is virtualy impossible to copy any recipe 1 to 1 without knowing the actual specifics that the mixer used
We all have the power...
But at the end of the day if your set on cloning a commerical recipe get prepared for repeated dissapointment.
It is fun but damn near impossible to accomplish 1 to 1
Good luck and best wishes
