It'd maybe be a useful follow up experiment to factor in more variables such as different tyre pressures, rider weight/mass, different speeds, track & arena temperature & humidity etc to get an even wider picture of the gripiness of the range of tested tyres across various conditions that may be encountered day to day.
It is interesting to note that the trl article says some other dual compound tyres are grippier by the measurement method used.
