There is a easy and simple way (just not instant) to determine where you are hitting the shuttle on the stringbed of your racquet aka contact point between the shuttlecock and racquet stringbed.
All you need to do is to restring with a darker colour string or your choice. This is the "old fashion" way, before the availability of high speed cameras etc.
After playing with it for a short period of time, you will be able to see the most common contact points via areas of wear & tear - see the example(s) from one of my racquets below.
With this information, you can slowly adjust your "stroke timing" until you are hitting the racquet "sweet spot" regularly (REF: see video on how to determine your racquet "sweet spot") - very easily said but extremely hard to accomplish.
That's the theory anyway ....
