Even with 10/fb of data and no discovery of SUSY valid regions might remain with fine-tuning less than 20. Moreover we investigate the fine-tuning price of GUT scale Yukawa coupling relations. Considering a 2$\\sigma$ constraint for $(g-2)_\\mu$ and fine-tuning less than 30 yields an allowed range of $y_\\tau/y_b = [1.31,1.70]$, which points towards the alternative GUT prediction $y_\\tau/y_b = 3/2$.
