There's no way he looks as good as he claims at his height.
I know you all don't like using sitting height in determining proportions, but his sitting height is around 93.5 - same as mine. Obviously, it's not completely accurate - but it's good enough to get a rough estimate. People with the same body length aren't going to have sitting heights that vary by 4-5cm. No, it'll vary by a matter of <1 cm.
Anyway, beside the point - his sitting height is 93.5. I believe him, mainly because looking at his stadiometer picture, he has the same torso length as me. At 188cm, a 93cm sitting height puts him below the 5duth percentile for SH/H ratio. Even if you doubt the accuracy of sitting height, it's hardly like he's actually in the 50th percentile for torso/leg ratio and his sitting height lets him down. No. We can safely assume his proportions are below the 5th percentile. To put that into perspective: that means in a room of 100 people, only 5 will have his leg/body ratio or worse.
Furthermore, My mockups clearly show I cannot pull off more than 6' - even then, I look quite leggy. I'm pretty sure I'll be doing 5cms on femurs and calling it quits. I'll be 180-180.5cm, in better proportion that Sysop, and still be a good solid height. I wouldn't want to be 6'2" anyway, I don't feel like a tall person - 5'11" is more than enough.
