[Callers] actual timing of calls for hey for four

hello - first time posting to this list so i'm sorry if I do it wrong (looked in archives and couldn't see obvious answer) I am going to teach and call my first dance with a hey this Saturday.. (ie tomorrow) our group takes things slow so i'd like to cue every interaction for the first few times, as our previous caller did.... I don't know how common this is but our previous caller would actually say-- ravens pass right neighbours pass left larks pass right partners left ravens pass right neighbours pass left larks pass right partner balance and swing I'm wondering if someone can clarify for me about delivering the calls for this hey....normally of course I deliver instructions so the last bit of instruction ends on the beat prior to the figure starting. But in the case of the Hey, if I remember correctly the caller actually called out the actions *as* they were happening.... Am I remembering correctly and if so is this the best approach? In essence-- do I start by calling "ravens pass right" *just before* they do it, or *while* they are doing it? thanks muchly :) Katherine Kitching in Hfx NS Canada
