As many lines You have as pb add, that amount of bots should be added there unless the amount of humans + bots doesn't reach the pb_maxbots value (yes - read the docs - the description for this settings says that clearly - humans + bots). The pb_maxbots is only for limiting all possible bots they can be added for example by pb add or pb fillserver commands. But if You want to have 5 bots to be there - just pb add should be 5 times there but pb_maxbots You can put higher - for example 10. So if You have at the beginning 5 bots there - You still can add some bots manually.
