Updated and Corrected version accounting for missing samples and with deeper clades (Clade depth of 11 from the first 3 digits)
Corded Ware has 20 / 135 samples on the same Clade as Yamnaya, which is a 14.8% similarity.

Another error was discovered after this chart was completed, which is that there number of Yamnaya R1b-L51 is only 1-3 samples and not the 7 it is in this Chart, so treat that part of the graph cautiously.
