I have not because with regard to my riding interests, the correct bike fit is the fastest one, a Retul or any other bike fit of this kind can not provide you with the information required to achieve this. Just look at the recommended range of angles quoted above as the recommended range, that is a huge range, one which could well be equivalent to several cm variance in saddle height, a range so large it could have HUGE impacts on both power production and aerodynamics, something a bike fit system like Retul can not evaluate.
I make changes (sometimes based on advice, sometimes on a hunch or educated guess, sometimes out of curiosity) and then using trial and error, test them in the real world, I then use Kinovea to make measurements where appropriate and record them.
The only serious thought I have given to a "professional fit" beyond going to the wind tunnel or having an aero testing consultation on a velodrome, is to get my cleat position (angle and side to side position) looked at, which I will probably do because I can not get 100% happy with the right foot.
