So I took the stem down almost an inch, would that make any difference possibly in seat height etc?
yes, seat height would be effected as well as fore and aft of the sadle angle.
meaning seat higher and back? higher/ forward etc… or would you say it can go many ways depending on rider? thnx
I had to raise my seat by about a half an inch, then the angle of the seat was titled down towards the nose about 2 degrees. Lastly the seat was slid backwards about 2mm.
With this setup I basicly rotated the entire body position in counterclockwise direction. Still is comfortable as my previous setup but I am more flat and aero now.

How did that affect your reach to the pedals? I know that sounds like a stupid question. But assuming your saddle was at the correct height before, isn’t it too high now?
with the added tilt in the seat, now it is perfect and the raise in the seat, I can sit more forward on the seat. Previously I was not sitting on the nose but further back.
i would first look at why you moved it down an inch. was it too high to start? have you increased your flexability? have you just become more comfortable in the position and able to feel in control with your weight on your arms?
then look at your postion before the adjustment, seat angles, drop, body angles, reach that stuff. what was good about it and what did you want to change.
was it too high? not agressive enough? a road bike with clip-ons?
did you come down to get more areo and also, now, want to also go more forward to a steep angle? (seat may need to come down, maybe not, and forward)
were you already riding steep and now you are just able to get lower? (seat might stay in same place)
are you trying to get more aero and forcing a lower position because you know it’s aero? (might need to lower seat)
An inch lower in front is a big adjustment. Seat needs to come forward a bit (1/4 in?) and maybe up a tad (<3/16 in?).
To visualize what is going on, take a paperclip and bend it into a two-dimensional stick figure of a cyclist in the aero position. Lay it on a piece of paper and put a dot at the foot and seat. Hold the foot in place and rotate the elbows down.
If your seat won’t go far enough forward you’ll have to accept a smaller hip angle. You might gain aero efficiency and lose power. …Might.
Also, you may have neck issues with such a large change so be sure to mark the original positions with some painters tape in case you wanna go back to the way it was. You can put a bit of tape on the spacers to identify the ones that you move to the top.

Sorry, man. You lost me at *“… take a paperclip and bend it into a two-dimensional stick figure of a cyclist in the aero position.” *
Connect the following 6 dots on a piece of paper: Ankle, knee, hip, shoulder, elbow, wrist.
Make the total distance along the dots from the ankle to wrist about the same as the length of the un-bent paperclip.
Bend the leg about 10 degrees. Bend the other 3 joints about 90 degrees.
Play with the figure on a piece of paper for a few minutes. Keep the angles of the joints constant and you’ll see pretty quickly how changing stem height leads to other changes.
