Ok this may seem a bit of a silly question but just how the heck do you calculate speed in sh4 (using the default/stock method)?
I Id the ship with the manual, use the stadimeter tool to get the range, input the angle on bow using the dial but when i goto the speed part of the tool i keep getting a message saying "cannot estimate speed, need more data", what more data could possibly be needed??
Ive even looked in the game manual (a first for me!) and i seem to be doing everything by the book but its just not working!!
