Just been listening to some of Terry Walton's podcasts on a long motorway journey. They're each about 30 mins and I find them very interesting. My wufe likes his sing-song voice too!
Anyway - his trick for broad beans is to take a handful of damp compost, chuck it in a freezer bag with a handful of broad beans, then leave it sealed in the airing cupboard for 4-5 days.
This way - all the good seeds will germinate before you put them in pots or in the ground and you;re not wasting time & space with duds.
Made sense to me so much to my wife's delight there's a bag of my broad bean seeds in with the spare towels today....
