Moving the seat back means it is probably higher than you started and perhaps should come down. Same rules apply to seat height. You may also find that the best tip for your seat has changed.

3'4" is a huge change. Almost like going out and buying a new bike. (I too consider 1/8" quite real.) But it sounds like you are on to a discovery of what works for you. Keep experimenting. (One equipment change that will make the experimenting much easier is a two-bolt seatpost. Thompson and some of the Nittos come to mind and there are others. Advantage is that you can loosen just one bolt, slide the seat and retighten without changing the tilt or loosen the one, make a small adjustment of the other, re-tighten the first and make incremental tilt changes.
