Lemurian,
Thanks for your advice, we always advise ATC of our A/C type on checking in with the approach controller, indeed in LHR for an example it is a requirement and still it didnt stop all the go-arounds.
The problem is you cant always advise the controller what speed you will be doing on the approach as it depends on the winds and not just the surface wind given by ATIS or ATC but the winds all the way down on the approach and these can vary from 143Kts to 200Kts depending on the config.
As said before G/S mini can be a great tool but sometimes needs tweaking...
