its like this.

at a running race there are two different types of runners.

runner A. he goes full sprint from the line and never lets up, but because he didn't save any energy his strength begins to die down slowly towards the finish line.

runner B. ah, this guy is conservative. he does a mediocre jog through half the race, and then just when he's falling back he goes full sprint to the finish line picking off opponent A. why? because opponent A was already tired and runner B was just beginning.

now, runner A = t25, runner B = gt35r.

put those together and you have the perfect power band.
