First things first, congrats NSF to your promotion...
As ever your explanation regarding G/S mini makes it for us simple souls easier to understand.
However, DESIpilot has a valid point, although not strictly applicable to the 320 series, for the A340-600 it is a common problem.
In my company there was a much higher than average number of go-arounds due to loss of separation between the preceding A/C and the 600 on the approach due to the G/S mini function especially in stronger wind condition this has lead the ATC having to increase the separation on approach.
I suppose a way round this prolem would be to go in selected speed until 4 miles then hitting managed speed however this could cause an un-stable approach if not monitored.
I think that G/S mini is a great function but still has its flaws.
