Your bleeding rules are a bit harsh because we have probably all experienced missing a saving throw 5 times in a row. It will be hard to balance the proper number of resolves for those times that bleeding does not occur with those times that bleeding removes so much resolve from one PC that everyone else is fine after one encounter whereas Ragnar the Punchingbag is on death's door because he couldn't stop bleeding.
To clarify, those bleeding rules are just optional gritty rules meant to simulate an event like puncturing the carotid artery. The type of situation where you're bleeding all over the place and have only a short time to get the bleeding under control before you're dead. It's included as an idea under the gritty options because it's deadly. That type of injury would probably only have a small chance of occurring on the hit location table, because it's so dangerous, much like decapitation from old critical hit tables.
You would still use the normal (ongoing damage) bleeding rules for conditions. That kind of bleeding might be dangerous if left unchecked, but most likely won't kill you.
