Speaker Placement - Frequent Placement Changes?

I use a speaker placement method to start with... then systematically experiment until I find the best placement, toe in and rake. 

I actually did follow chatGPT recommendations on my speaker placement. A combination of placement, distance from listening position & front wall, speaker width & toe in, plugging one of two rear ports, top on one, bottom on other, changing port tubes, & equalizing my sub via a miniDSP, I was able to achieve a flat response & great soundstage & imagining in an asymmetrical room. 
 

My experience is similar to the comments by joeycastillo that REW is a great benefit to provide objective information to optimize placement.  Prior to this I was constantly chasing adjustments which, I'm sure, in many cases were not real.  I also used REW for upgrading my acoustic treatments.  It's quite amazing how seemingly minor changes in both treatment and speaker placement show up in REW profiles and RT60 data.  

I believe REW helps in gross placement of listening position, mains and subs, but when I make minor adjustments of a half inch or a couple degrees, the data does not really change. The ear rules once you get close.
