Audiosnap still a mystery to me

I am still not able to get a handle on Audiosnap. Haven't used it much for this very reason.

The "Clip follows project" function effect eludes me. For example: after bringing in a rhythmic and simple audio clip I turned on Audiosnap and edited the clip's tempo map. Not too much was needed to align the "beat-1" markers with their appropriate transients. They were just a bit off and it is a short clip so not too much work there, but if it were a long clip it would be quite a pain. So,first off, isn't there an automatic function to adjust a slightly inaccurate tempo map? (i.e. sliding tempo map beats to the nearest transient? - in the case above, that is exactly what I manually did to correct it.)
Here is a section showing my tempo map edited clip with the map and project tempo out of sync:

Before

Then I pressed Clip follows project (with the Measure option selected) in order to have the tempo map corrected but slightly varying tempo clip align itself to the constant project tempo. It changed but did not align itself perfectly with the project tempo!? It started wandering away after a bit. Here again is that same section after choosing Clip follows project:

Choosing the other various options for Clip follows project (i.e. Beat, Clip or Auto stretch) failed to align the clip's tempo map to the project tempo. Nor did choosing the Set Clip Tempo from Project on the Average tempo drop-down as suggested in the Help file.


In comparison: Ableton, though not flawless, imports audio, tempo maps it and aligns it to project tempo almost seamlessly if it is not too off (if you have warp enabled) with no further editing needed in some cases, certainly with the above example.

I am apparently missing something fundamental here and would really like to understand Audiosnap better...

    In fact, I can't get any function to work in Audiosnap to work the way I assuming it will work. I simply cannot get transient markers to line up with tempo map markers and to then line those up with project tempo delineations, even working on a simple kick-snare quarter note rhythm! It sees this clip and defaults to an average tempo of 0!?! I tell it the average tempo is 130. It starts the map at 0:2 (?) Neither "Clip follows project" or "Project follows clip" will line up beats accordingly. Quantize makes the beats further off than they were!  - All this on a simple, quarter note, kick-snare audio clip (played slightly in and out of time for the test).



    What I expected:
    -Input a file that is a little off time
    -Audiosnap maps a tempo aligned to what it thinks are its beats
    -Audiosnap then is able to align those beats and that map to a controlled project tempo map by stretching or compressing.

    All this I would hope to happen more or less automatically, but I have to manually move almost every beat myself. Now, obviously the issue here is me. I just do not understand something about Audiosnap (or maybe anything). The help files give me no clue as to the basis of operation here.
    I don't want to take of too much time here. Is there a book on Audiosnap? A website? A movie? A religion?!?

    I agree that it's difficult to understand. The documentation is also not that understandable, at least to me. Even if someone out there knows a good resource to read that could explain all of this a little better, that would be helpful.
