From the link provided by Testudo, you can now have an idea what these settings do. [img]/images/graemlins/smile.gif[/img]
For the settings issue, actually there is no "best" setting for the Script Assure. You just need to find the setting that suits you. [img]/images/graemlins/smile.gif[/img] For example, set the MARS, Warn, and LCRS in higher setting if you want to be more lenient. Lower if you want to be more strict.
The Ambi settings is used for comparing two objects' recognition score. And when the difference of the two objects' score is lower/equal to than this setting, RFT triggers an Ambigous recognition exception error. This basically means that it can't recognize what is the right object to perform the action to.
So if you want to be more strict, set the Ambi setting to higher value, lower if you want to be more lenient. It is different with the other 3 settings.
