Within 100 yards the arrows can penetrate most shields and armours easily. English longbows can hit 300 yards far..
Depends what armour you are talking about.
A longbow or close equivalent, will go through chain mail, reasonably easily, with the correct tip.
Chain mail piercing tips are long and sharp, platemail 'piercing' tips were shorter, but still sharpened at the edges.
The actual success rate of a plate mail piercing arrow is VERY low, even at a range of 20 yards, this depends on the workmanship of the armour also.
Any angled platemail will leave the arrows just bouncing off, with flat plate mail, you may get a dent, but it usually just cannot penetrate the armour.
I have seen a platemail piercing arrow piece some metal, the same kind as was used in most platemail, the problem was, this was a large sheet of metal, due to the added flexability of the large sheet, and arrow could penetrate fairly easily.
Longbows were lethal against armoured troops not because they reguarly pierced armour, but because they were fired in such hails of arrows, that out of the 100 that hit you, 1 would go through and kill you.
Basically, people would not of bothered wearing plate mail unless it actually worked, which is why it was worn until guns became common.
