No, but that's why you aren't a lone archer on the field. You're in a block of dozens, and you're behind a block of billmen who stop anyone with a hand weapon (bill, sword) from getting anywhere near you.
If that fails, and someone is anywhere near 20m, you drop your bow and a) draw your own hand weapon, or b) more likely - run. Because if you're up against someone whose primary weapon is a sword, they're likely to be better than you and have more/better armour, so your odds are low. On the other hand, if you're up against a billman, your odds are basically zero.
I only put the accuracy for a 20m target because a) that's what we shoot at for practice in my reenactment group, and b) to demonstrate that most people can aim moderately at that distance while shooting quickly - they're not just pinging arrows off in any direction in order to get the rate of fire up.
As a longbow archer, your primary job is to put as many arrows as possible into a large block of men 200m-300m(-400m?) away before they get to the billmen you're protecting (and who are protecting you.)
