You have discovered that running naturally and relaxed will produce the result which is most desirable.
If you have cues you need to make sure they are the right ones.
For example for years I used to run with my shoulders up. It’s easy to tell myself " shoulders down", as this que reminds me of some grade school coaches yelling from the side lines… " run faster". It was not until I became more comfortable with the work I had put in and started to see my training times fall that I could relax more.
I think your question is an excellent point to discuss.
