Hi i am new, and cannot get my head around the torpedo charts. at first i thought that the filled circle used the left side (Standard) and the unfilled used the right (Long Range). however this fell apart as i looked at different nations the Italian has 2 range brackets on the STD side but the 3 &4 black circle has rolls in the bottom line.and the clear circle on the right which has a 3rd range line in Long Range does not have a roll in the bottom line. the Brits have a third range line in Standard but no black circle die rolls listed. the French are the most confusing, they have no clear circle torpedoes but have only one range band on the left but rows 2 and 3 have die rolls listed. i now have no idea how this works
help
