If the staff reading is high it means the station point at low level.

If staff reading is more it means the point is at lower level. Here the B.S is more so the point is at lower level.

No, explain this how is the station is at lower lever by it reading is more?

Suppose we are doing levelling on an elevated area so if the reading comes on the staff of B.S is 20m and F.S comes 15m through the help of intermediate side so off course B.S is at a low level.
