I don’t use one much because I mainly stay with known loads and my shot distances here are 200 and under so it really isn’t necessary.
Just relating my experience with the chronys vs the oehler. Chrony did miss more readings but they were basically equal.
There's no reason for most people to own a chronograph. If you use tested loads from a manual and are taking shots at 200 yards or less, you don't need one. Please don't feel that your response was unappreciated.
All the best.
