It all is a matter of equipment.
With a NanoVNA, you are limited by the number of data points the the sampling rate those points are read. While using an NanoVNA, it, indeed, is touchy and time consuming. While using an oscilloscope with a tracking generator, you see the results instantly and tuning is a breeze.
Also the dynamic range makes a huge difference. You have a hard time if your signal drops into the devices noise level when locking for a minimum. I am lucky to know people with the right equipment.
