It is likely that combinations will create difficult to pronounce or remember. Such is why you should create a batch and then choose one that works for you.
I do not want to start adding too many creation rules as doing such can make it easier for a hacker to eliminate possibilities.
Another way to use it is just click your browser refresh when viewing the results page. A new set of passwords will be generated. If you do not see one that works for you, just refresh again until you find one that does. If you are generating multiple words per password, nothing prevents you from mixing and matching from multiple entries to create your own.
