We're all different, physically. I frankly need them. After just one day of inactivity my legs are sluggish and heavy. I've discovered that not only do I need the openers to keep that from happening, but that I perform better if I stress myself for a few minutes during the openers ride. That means, for me, up to LTR (or higher) for a few minutes, and then ramp down. I hit it again one more time before I finish the ride. Because my matchbook is pretty small, I have to be careful about the stressors, and not use up needed match sticks. I've had to learn, by doing it, what is too much and what is too little for an openers ride. One hour is just right. Forty minutes is too short. I have to hit LTR, if I don't, I have muck for legs the next day. My world!
