I'm giving a preso at an upcoming major IEEE conference and they run training for their speakers, distribute a training pack and template. Amongst all of that was this guidance: "• 10/20/30 Rule • (10 slides - 20 minutes presentation - 30pts font)" Now it wasn't perfect either and we also had the accessibility conversation about the colours chosen in the template. This is just FYI - I'm not expecting the equivalent but food for thought. -- Narelle narellec@xxxxxxxxx
