t7, I am sure they do. IIRC available settings were 0.09, 0.18, 0.24, 0.30, 0.45 etc. Whilst is would have been possible to set any of these there was a practical minimum that would minimise jostle. IIRC that would be 0.3.
At 360k you are talking of around 200 yards per second. 0.03 would therefore give you an interval of 60 yards.
Looking at a crater line on Google Earth I make the interval 53 yards. This suggests, at 0.3 interval, a speed of 315 kts.
My recollection is 40 odd year ago but I think it would be about right.
