I wrote and released the embarrassingly simple skill " parallel inductance". It teaches the user how to calculate parallel inductance by calculating the inductance of two coils. I tested it many time with phrases like 5 milliHenries and 5 milliHenries. Recognition of the sample phrases was not perfect but was pretty good. MilliHenries was always understood.
The skill has been released for around a week and has seven users. I imagine they have given up because it no longer recognizes the word milliHenries. It is as if it has gotten 'negative' training from the users. Weird. Is there a way to 'reset' this condition to restore recognition the the state it was in when I released it?
