This is true, but there is no external comparison so it has little to do with my question. For example say that by squatting
without utilizing the stretch reflex someone took their squat from 125 to 395. Are they necessarily weaker than someone who took their squat from 135 to 405
utilizing the stretch reflex? Maybe, but it isn't obvious. They are different movements, it is conceivable that the stretch reflex gives you a few extra lbs simply by storing elastic energy. Why would I expect this to translate to strength in any other context? It might do, I'm just asking if there is a reason to think this.
