I had a Retul fit recently.

Mind blown.

I went from an aft slammed saddle to one all the way forward on the rails and the need for 150-160 mm stem, but really a new frame. The basic process was video capture and automated analysis of various angles, which have ranges of acceptance. My pedaling was good, only 1 degree of movements.

I was told to expect a lot more power.

Color me skeptical but hopeful.

When rested properly I am going to repeat my 3 minute local interval hill. A few days before the fit, I did a PB in time and blew away my previous best on power for that duration. I have done this 10-14% hill probably 200 times and know that 2-3 seconds improvement would make the fit worth it but the real test is whether I can ride with such a forward bias of my torso and it addresses some pains that I have recently been having. I have always preferred the Greg Lemond type position. I'll see within a few weeks. If it works, then, need to find an appropriate much larger frame or bike in stock.
