Worm's Raiment, Hircine's Veneer, Ebon Armory Set question

MaiWaifu

As you might have known, the 5 piece bonus for the Worm's Raiment, Hircine's Veneer, and the Ebon Armory sets are reduced magicka costs for up to a group of 12 people by 5%, increased stamina recovery for up to a group of 12 people by 10%, and increased health for up to a group of 12 people by like 1000 health. My question is that let's say there's a group of twelve people doing trials that are all wearing the Worm's Raiment set, or the Hircine's Veneer set, or the Ebon Armory set. Will they theoretically all get 60% total reduced magicka costs, or 120% increased stamina recovery, or 12k health respectively?

Never tried it with hircine or ebon, but worm's raiment doesn't stack anymore. They changed that long ago as it was too strong.
