When you order a steak, the levels of tenderness degrade the more done it gets yes? When you strike that perfect balance between medium and rare, you will see that the steak is firm-ish while being tender at the same time. What exactly are you trying to say?
Well, no, you're oversimplifying a complex issue. Tenderness is dependent on many factors, and the internal temperature can influence that. People misunderstand why meat is tender and why it isn't. It is usually not dependent on the internal temperature achieved, but rather the way the meat was prepared, the way it was cut, the type of cut of meat being used, the cooking method, the resting period, the fat content, the type of fat content, the utensils used to eat the steak with, and a host of other factors.
I can assure you that I can cook you what will appear to be a perfectly raw steak that is incredibly tender. I can also cook you a well-done steak that is perfectly tender. Yes, temperature is important, but thinking that it's the determining factor is incorrect...
