I agree that seeking fit advice on forums is near useless, as everyone is different and we can't see what is going on.
However, one piece of advice I encourage you to adopt is to MEASURE your setup and keep notes. Things to measure before and after each change are 1) Seat hieght from the center of the bottom bracket to the top of the seat, measured along the seattube, 2) The saddle nose to the center of your stem (for setting fore-aft saddle position), 3) The height of your hand grips to the floor (in case you tinker with changing the height). 4) saddle tilt angle, you can use an app on your cell phone for this, and measure using a flat board on top of the saddle.
As mentioned, changes of 1cm are large. I prefer to do 5mm changes each time, unless I know things are way out of whack.
Oh, and run from any saddle position mention that mentions 'KOPS' - It has no scientific/physiological basis.
