What on earth are you trying to do flying at 10 knots over the stall speed while doing a performance landing?
Do you know how much extra energy you having to get rid of by carrying an extra 16% speed?
No wonder you think those fields are tight. Try doing a glide appoach at a more suitable 63knts and see how little runway you require.
Round numbers of ground speed Mad Jock, if you think you are going to come in at perfect stall speed, 4 up as in this crash, fuel weight not known, wind strength and direction not known, under extreme pressure, then I think you are kidding yourself on your skills while under an extremely stressful situation.
Best Glide speed btw is 87-88 knots but that is not relevant to landing or approach speed.
Much better 17 knots vertical speed in the scenario of this accident,
