So today I decided to put my Physics knowledge to the test. It wasn't too hard to figure out but a bunch of my friends went into a private match to find out how much the perk Impulse Amplifier increases velocity by. So a normal Code Duello with no perk and the same velocity stat traveled at around 26 m/s. After that we tested a rocket with the perk and its velocity noticeably was better and it clocked in around 33 m/s. We did some percent difference equations and found out it was roughly 28% increase so Bungie probably has it at 30%. Thank you all for reading and feel free to spread this information!
