I'm 6' 0", 35" inseam and I ride 61cm frames. Your chart says 59. Maybe on some frames a 59 would work, but not anything I ride.

Geometry can a have a huge effect that you do not account for in your measurement. Top tube length and head/seat angles can change fit significantly.

Also, while the reach may be the same on long and short torsoed riders, weight and musculature distribution is not. That also may influence ideal top tube length.

Finally, I'm not convinced that extra foot length is equivalent to extra height, especially as crank lengths change.
