3- To use the "speed" estimation tool in Notepad, you need both the type, the AoB and distance inputted before going for the speed. Al of the above data is used when evaluating speed. If your data is solid, 30 seconds is enough to get a working speed to input.

o_O no need to do calcule like that.
Use the 3min15 méthod then first mark with the second one give you the speed of the targe thats it.
You can also use 1,37 min.
1,37 x 2 = 3,14 so very close to 3,15
using 1,37 if you get as a result 0,4 you do 0,4 x 2 = 0,8 speed of target.
