Once heard of an older Okinawan master demonstrating a sai technique. He held the sai a particular way and was asked by a student why he held it that way. The student had seen the same technique applied a slightly different way. The master nodded and demonstrated the technique both ways, indicating that either worked just fine. He replied "Young guy do, old guy do." Meaning that one method was taught more in older times, and many older students still did it that way, and now it was often taught with a slightly different grip, and younger students often did it that way, and both worked.
I have seen stances that differed slightly between students of the same art. Both stances were quite stable, both worked fine for generating power. Young guy do, old guy do.
I saw a very tiny detail in a foot during a kata demonstration, a slight lift to the edge of the foot. I asked if it was intentional. It was. I asked why. Smile. Young guy do, old guy do. I wasn't satisfied with that and practiced until it started to work for me better with the blade edge of the foot slightly lifted, and worked on it more until I thought I understood why it was better. Young guy do, old guy do.
Sometimes, details matter. Sometimes they do not. Sometimes the student has to figure out what old guy knows that young guy does not. And that is actually the point of the lesson sometimes. Only those who care to dig will find solutions. For others, young guy do, old guy do is enough of a reason to stop looking.
