And the phrase 'no matter how' contradicts at least one magic item I know of, not to mention contradicting cleave.
Which magic item is that?
As other feats maintained 'highest bab', and this feat says 'same bonus' - I tend to disagree. Especially since agreeing would open the door to many more equal questions (what bonuses are legal for cleave?) to which there is no easy response beyond adjudicating on the spot.
I don't agree that there's no easy response.
If I have a BAB of +6, then I can make two attacks. Let's say I swing at the hobgoblin, and then at his Dire Wolf buddy.
The first swing, I take a BAB figure of +6, and add any bonuses that apply. Strength, enhancement, flanking, Bless spells, Bardic music, higher ground, Bane weapon, whatever.
The second swing, I take a BAB figure of +1, and add any bonuses that apply.
If we throw Cleave into the mix, then I calculate my Cleave attack exactly as I calculate any other attack - take a BAB figure, and add any applicable modifiers. And the BAB figure for a Cleave is the same as the attack that dropped the original opponent. Unlike many other feats, when the BAB figure you use is always your highest.
There's nothing complicated or arbitrary about it.
