You could, but you won’t learn much from it. It might give you a sense of what a normal approach should look like. Otherwise its just a lot of practise. Easiest way is to really focus on the aiming point markers and nothing else, you will be able to see immediately if you are flying straight towards it or under / overshooting.
There was a discussion before about landing techniques in the forum and I decided to check what I am actually looking at and focussing on during landing, this happens subconsciously after so many years, I thought I might have adopted some techniques or habits I wasn’t aware off.
I found that after flying for 12 years of flying professionally. I’m still doing exactly as I was taught in flight school. On final approach crosschecking between speed and aiming point, far out or in less then ideal visibility maybe a crosscheck with vertical speed. Then focussing towards the end of the runway upon starting the flare. I have been an instructor before so maybe it became hardcoded
