I typically use the default break settings, so I'd recommend them. But keep in mind that break settings are really a personal preference, and lots of people skip breaks and some people have very short frequent breaks, etc. Ultimately I just recommend botting like you might play, including with break timings.
Anytime I use the bot the first attempt I may get the kill but any there after It makes many mistakes and dies. The first attack is never prayed against or is prayed late. This happens a few times in the kill which leads to most deaths
