hmm i was always told 1,3,5 and thats also what the wiki says.

Wikipedia's are mostly free to edit by anyone. Information is not always accurate.

I've found one page about the bows supporting my fact: http://www.minecraftwiki.net/wiki/Bow

Some pages may differ but 5 hearts is actually a critical according to the code.

a fully charged bow is an auto crit so always 5 hearts
