preinfusion time part of full brew time?

Hey all, pretty new to coffee in general, just decided ditch the energy drinks and move to coffee going forward. Grabbed a Gaggia Classic Pro and tossed a gaggiamate on it for a bit more control. A question that I cant really find a firm answer for and Claude/GPT seem to be at odds a bit. Does the preinfusion/soak time count towards the full 27-30s (roughly) brew time, or does it start after the soak? Thanks in advance!
