Can you validate this comment please? Meanwhile some guys not only walked the stage before but shot it once.
As per IPSC rules which cover the rest of the world, the mandatory 3-minute walk through after stage briefing is applied, no one pre-shot the stages or walked them. And yes, you had 3 x minutes to walk the stage work a plan and then execute when called to the line, with no sight pictures at make ready or stalking in-between the next competitors run.
