That is a good point. Of course you're no less likely to have a jam at 10 yards than at 300, but at 10 yards you are certainly less likely to have to 'walk' your tracers onto the target with a long hosing burst, so you probably would be statistically less likely to suffer a jam at close range simply by virtue of the smaller number of rounds you were putting through the gun, unless you were unlucky enough to have your first shot jam.

Which brings up another point, for the Brits, Frenchies and Yanks, that being the small magazine capacity of the Lewis, which probably meant walking your fire onto a target at range would needlessly waste a large proportion of the available shots one had, since you'd almost certainly not be able to change drums on the Lewis in the middle of a dogfight.
