Una mas, my only consolation was that I was shown four or five Oxford birds at flight safety that had done exactly the same thing, only worse.
I found that various flying schools had a habit of adding 5 - 10 knots to approach speeds for no good reason. The only exception was Tvsa(?) at Bacchus Marsh who made it a point of honour to hear the stall warning as your mains touched.
Once I learned the correct approach airspeed of 55-60, holding off and the Jacobsen flare, no further problems.........yet.
