The final number I came to matches closely to the one that frame size calculator on Specialized web site recommends me for a road bike. So I reckon it's more or less fine now.
A differential of 5 cm has alarm bells going off for me.
Can you post either a video from the side of you pedaling on a trainer or a photo with your leg/foot at the bottom of the pedal stroke?
I went to the Spesch fit webpage for giggles, it did my saddle height correctly but put me on a too small frame. HOWEVER.....if I added a mere 1 inch to the knee to floor distance....it increased my saddle height by 3.49 inches. SO, this software is ****.
Typically unaccounted factors that affect saddle height are cleat position, crank length, pedaling technique, and physical issues a rider could have.
A high proportion of riders have saddle too high. A long distance rider is better erring on the slightly low side.
