Actually, to an extent I agree with some of the things that Mickma and others have said in this thread.

I used to work for a software company (Sonic Foundry, now Sony Media Software). In the training department.

Training documentation and software documentation were indeed two separate departments. The reference manual went into "push this button to do this" and they kept it short and sweet. The training material went into specific examples as the user would actually apply them.

Both approaches have their place ... but unfortunately specific tutorials can get very wordy. To do something extremely detailed and thorough for all of the features in something like Poser would take many many pages. I bet at least 1000 or more. And something of that size is costly to print, so it's left to PDF or third party.
