Rate of Fire error

[justme262]

Has anybody else noticed the rate of fire in the hurricanes is higher than the rate of fire in the spits?
If I load the outboard guns with tracers in both planes the hurricanes clearly have less distance between the tracers. Almost a constant stream of tracers. The spits have large gaps between each tracer.
Same tracer types...I've tried a few different types. A single tracers in number 1 and 8 guns in loadout screen.
Maybe it's a graphics glitch...
