The soil profile at a construction site is shown in the figure (not to scale). Ground water table (GWT) is at 5 m below the ground level at present. An old well data shows that the ground water table was as low as 10 m below the ground level in the past. Take unit weight of water, $\gamma_w = 9.81$ kN/m$^3$. The overconsolidation ratio (OCR) (round off to two decimal places) at the mid-point of the clay layer is ________
