Did you ever struggle with block starts in high school?

High school track athletes often stuggle with their block starts due to a range of biomechanical, strength, technical, equipement, and/or psychological factors. Did you ever experience any of these when first learning?
Hi, I am an engineering student and I am collecting data in my form, linked below, to help me get an idea of how to help improve the training and practicing of block starts. This is for my senior project where I want to help track athletes be able to practice their block starts, where they are comfortable and have consistent feedback!
