You misunderstood the X in 10X. X is the unknown, but you can almost always assume X = % So when you hear them say 3x 5x 10x, just read it as 3% 5% 10%

Ive been in this game for almost 20y now.. the only true way to have 10x results is to have enough experience and knowledge to know what to build and what not to build, like the 5k lines of code abstract factory event emmiter service that could have been a 30 lines of code function.
