Estimating target speed

ninja turtle · 04-27-13, 03:56 AM

Hi guys

I've been using the 3'15 method with success but I've also seen tutorials on youtube and read that you can use 3'30. Does anyone know which method might be the most accurate? I'm just curious why there are two measurements.

Thanks and good hunting

One is for Metric, the other is for Imperial.

Aha!! Thanks Reaper for the quick reply. That makes perfect sense

One more question, though. Which one is used with which?

I sound quite dense

Hi there, I believe that the Germans used the 3' 15", and the Americans used the 3' 30". The Germans I am sure used the metric numbers and Americans the imperial.

Americans used 3:00 precisely. 3:15 is adjusted for metric. I don't know where 3:30 comes from, as this is the first time I've ever seen it mentioned anywhere.

So were these methods used operationally? How did they do that without 'map updates' in real life - I've never used that method because I play without updates on, I always thought 3' 15" was a game method only.

If they plotted it, surely that's not as accurate as the U-jagd or the periscope scratchmark method on OLC GUI?
