on the 17 and 24 there are 4 tick marks between N and 30 so 7.5 degree divisions. between S and 210 its 3 tic marks, 240 and W its 5. Isn't it normal to have 5 degree tic marks? On the B-26 there are 15 tic marks between cardinal headings so 90 divided by 16 is 5.63 degrees?
Is this based on anything? Its pretty impossible to use well. Also they seem to be spinning backwards. What gives?
