You may be the first short person I've heard from that may have more leg length to height than I do. I'm 168cm tall with an 83cm inseam and 73.5cm saddle height. I see nothing unusual about the bike that you have, but you haven't mentioned any details about the stem length, stem angle or spacers under the stem.

I would pay absolutely no attention to the ouput from the CC fit calculator. It's just about worthless, IMO.

FWIW, I ride a 51cm LOOK 585 that has a 74.5 STA, 53cm TT length and 125mm HTL. I have a total head tube stack of 145mm, with the headset and one 5mm spacer. I use a 73 degree x 110mm stem to produce about a 12cm drop from the saddle to the bars. I use short reach Easton EC90 SLX3 bars to help keep the stem length at 110mm. No stubby stems for me.
