IF you are calculating for either:

NON AGE STATEMENT (NAS) Whisky OR any whisky younger than 8 Year Old, then please enter the age as 8.
This is due to how the value score calculation works, for the purposes of the algorithm, any whisky which is less than 8 Year Old or a None Age Statement must be entered as 8 Years.

Finally the price field has to be in whole £ for this purpose we recommend rounding up or down to the nearest whole £ (its a glitch in the matrix)

The value score is based on analysis and research of whisky data.
I continue to monitor it effectiveness for the purposes of future adjustments in how it is calculated.
