right explanation of impulse being faster than wally based on what i know from the comics:

the speed force is what gives speedsters their power, wally at this stage in his career in the comics was slower than barry because he had a bit of an inferiority complex (in my opinion) about having to live up to barry so that limited his ability to use the speed force. eventually in a time of great stress he had to go faster and finally ran faster than any other speedster. bart on the other hand doesnt have this inferiority complex so he uses the speed force to his fullest extent.

dont hate on what is set up for character development without considering why something has been done or until you see the pay off. i expect wally to have to break his linit to save artemis by the end of the season by the way
