When we offer bounties on our own questions, we are given the options of 50-500 reputation in increments of 50. When offering bounties on questions posted by other users, the increment is the same, but starts at 100 instead of 50. Why is that?
Note: The FAQ states (emphasis from FAQ):
Slice off anywhere from +50 to +500 of your own hard-earned reputation and attach it to any question as a bounty.
EDIT (Feature Request):
Can we get a note added to indicate that this is the case when starting a bounty?
