It is important to record hand written notes and the order the where taken in. For example when writing math notes, you can be working on a problem and write all around it with note or cross something due to elimination process of the problem. When reviewing the notes later on it can easily be confusing when the original problem has been marked up. That’s where stroke recording can come in handy. You can watch your process replay in front of you and see your own problem solving process. This is very important especially for students and STEM field workers
