Simulating "Rack Delay" in Focus Ramping...

[mSpider]

Hi,
I would like to make a time lapse with focus ramping.
Is there a way that I can have the intervalometer shoot a number of shots before the focus ramping begins?

yes, automate it with picoc

That would be great.
If anybody knows where I could go to start the process of learning how to do this, that would be great.
I'm not even sure whaat picoc really is, and have no programming background...but would love to start.
