Because the software has no idea what a groove is, its not programmed 
that way.

Same reason as above.

Certainly a computer would be able to do that, but I also have the 
problem, that I never found an "algorythm" to incorporate it into my Max 
patches. Though I think it should not be too difficult. It just has to 
do it like a good drummer does it. (So far all beat matching toys are 
just very bad drummers)

The software has to predict when the next beat will come, and play its 
beat at that moment, then if its off, adjust its own modell to predict 
it better for the next beat. Just averaging the last beats will always 
lead to results which are too late. How else should you be able to track 
an acceleration or a ritardando?

The other approach would be to give the drummer a pad to directly 
trigger the loop each time. You could even determine a stretch factor 
according to the time between triggers for the next playthrough of the 
loop...

Just some thought of somebody who build usually his tools all by himself...
