Again, a PPRuNe storm in a cup of tea...
Go around as described in situation above (below Vref) is -

GO AROUND THRUST
FLAPS XX (say setting for your airplane)
PNF announces "POS RATE"
GEAR UP
Go around at Vref
The initial scenario described the situation where the speed had decayed up to 15 knots below Vref when the go-around was initiated. A bounce or extremely long high float comes to mind. In other words a low energy go-around. It would be incorrect and potentially dangerous to immediately select Flap 15 from Flap 40. It is not a normal go around procedure under the scenario presented and would not have been published in the AFM.
In fact the situation as described is approaching a stall recovery. In that situation you do not touch the flaps or landing gear while ground contact is imminent which it certainly is here. Only when the aircraft is climbing away from ground contact and speed at Vref or more would the normal go-around procedure apply.
While the remark was light-hearted I would not refer to the whole thread as a Pprune storm in a tea-cup. A low energy go-around with full flap and landing gear extended especially on instruments at night, is deadly serious flying and requires careful handling.
Read another recent Pprune post linked to a Canadair CL-5 crash after a low energy go around from idle thrust in IMC fog. A comprehensive report from Canada that recommends manually flown IMC go-arounds from the flare are important simulator training exercises. Most IMC go-arounds are from Cat 1 ILS minima or on full automatics via Cat 2 or Cat 3 ILS.
