Are betting systems equally useless when you have an advantage?

Quote: Talldude90

In general, wouldn't betting systems be a defined boon in a +EV situation as long as you are not raising your RoR significantly? Wouldn't you be getting a lot more coin-in against the +EV (as long as the system dosen't lower your EV), so your end profit should be bigger for a set amount of time gambling (say 4 hour session)?
