So I recently got a new bike (Triban 500 RC). And I've been thinking recently that I haven't properly set my saddle height. Couldn't put my finger on why but had a feeling it could be better. So got home and as accurately as I could did both the 90% (to bottom bracket) and 109% method (To pedal). Both show my saddle to be about 4cm too low!?!? Eh?? That just doesn't seem right. I would surely notice that? If I do the "heel" method then it shows my saddle position to be give or take perfect. I'm thoroughly confused. This is a photo of me at my bottom stroke (in line with seat stem) if someone can tell me how it looks I would most appreciate it. I've measured the angle drawn in Photoshop and it's bang on 30 degrees.
