Comparing profiles can be difficult. The eye test will certainly get you close, but the Terpene Calculator will calculate a percent similarity. Here's how it works.
Terpene Ratio Similarity is calculated first. This calculation looks at the similarity between how many terpenes make up the profile and the ratio of each terpene to the total profile. The formula factors in each terpene are present separately.
Terpene Concentration Similarity is calculated separately. This calculation looks at the similarity between the concentrations of each terpene in the profile. The formula factors in each terpene's concentration separately.
These two similarity scores compare the profile in two different aspects; one focuses on the terpenes present and how much each terpene contributes to the total profile, while the other focuses on comparing the magnitude or level of each terpene present. If these two scores are close to each other, they are considered a Class A match. As these two scores increase, the confidence in the similarity calculation decreases.
Class A Similarity - 0-10% variation between similarity calculations
Class B Similarity - 10-20% variation between similarity calculations
Class C Similarity - 20-30% variation between similarity calculations
The Mutagenesis Generational Ranking (MGR) categorizes strains based on lineage, tracing back to landraces. Think of MGR as a "coded genetic tree", indicating how far a strain is from its landrace ancestors. As each generation increases, the genetic line becomes more hybridized and removed from landraces. Backbred-crosses are tracked by adding a "b" designation, while inbred-crosses are tracked with an "i" designation.
Generations:
G0
G1
G2
G3
G4
G5
G6
Designations:
i - inbred
b - back bred to a previous mutagenesis generation
