100% agree, people lose out by not fully contracting hard at the top, high up on their toes. When I started training back in the day you would get ridiculed for cheating or not going through full ROM. That was when gym comradery was part of gym life, no headphones or ear buds, they didn't exist yet. Music blared through the gym speakers and everyone trained to the same music in the background. Guys in the gym were your bros, evening gym sessions were your social life. Hard to believe, right.
We just trained different back then, including calf training was a part of ever leg session. We trained our calves in different planes, standing and seated. Remember donkey calf raises, if the gym was serious enough there was a donkey calf raise machine in the gym. Just a different mentality these days.
