[DC] If Barry Allen generates the Speed Force, how is Wally West the fastest Flash?

Basically, while Barry is the source of the speed force, Wally has a more efficient mechanism for using it.

Think of them like electric cars. The Tesla S and D use the same battery technology, but the D has a better (pair of) motors, and can accelerate more quickly and achieve a greater top speed.

Barry's generation of the speed force is the batter technology, which Barry and Wally share. Separate from that, Barry and Wally are both able to draw on the Speed Force, which is the motor.

Or, using Star Wars as an example, all living things generate The Force, but some individuals are much more adept at using it.
