Thanks for the help. Help should I interpret the numbers ate Medium
and Long range? Since they are negative. (e.g. -15 cm)

About the conversion to 25mm 1.1 states that you should double the
distances for 25mm figures (I use use 1:72 which is 25mm if I am not
mistaken).Thus a bow has a short range of 0-10cm, which doubled is
0-20cm. However when interpreting the numbers as inches you get the
following 0-10" that would be 0-25.4cm which is a big difference.
Hence my question which measure should I use for my 1:72 figures?
Thanks again.
