Is there a benefit to "pulsing" the Mantis machine gun?

When playing with the Mantis (as I am lent to doing extensively on the "Two Giants" Spartan Ops in Episode 3) I find that the machine gun overheats constantly. In past games, I found out after quite some time that there was a benefit in accuracy to "pulsing" the certain full auto weapons - particularly in accuracy. For the Mantis, I'm also interested to know if pulsing it will extend the amount of time before it overheats. Experimentally it seems like it may be extending the overheat time, but I can't really tell what other affect it may be having (reducing DPS, for example). Is there a benefit to pulsing, or am I fooling myself?
