Either way is fine. There will be no appreciable difference.
This isn't mashing, no conversion. Only washing out sugars that are already there. The water to grain ratio is all wrong for mashing.
I recommend steepers use the same kind of water/grist rations that you'd use for mashing. Not only does that get them in the groove if they want to mash, it also insures there won't be any tannins extracted due to a high pH caused by using too much water.
