FastBreak is a Minecraft hack that allows the user to break blocks faster than normal. It works by sending a “block broken” packet to the server before the block has actually been broken.

The “Activation chance” slider randomly disables FastBreak for some blocks, if it's set to a value lower than 100%.

This works great for bypassing anti-cheat plugins, because they can't really tell the difference between FastBreak and a laggy connection. A few blocks being broken too early can happen in both cases, so these plugins only suspect FastBreak usage if they see a lot of blocks being broken too early in succession. Randomly disabling FastBreak for some of the blocks breaks up the pattern, which leaves these anti-cheat plugins clueless.

A value of around 50% seems to bypass the Vulcan anti-cheat plugin quite reliably, while still providing a much faster mining speed than Legit mode. Though it's possible that even higher values will work, too.

The “Legit mode” checkbox disables the speed-up effect of FastBreak, but still removes the small delay between breaking blocks. This is useful as a last resort for servers with very strict anti-cheats where nothing else seems to work.
