Comment 1 for bug 1390346

I would guess that with "assume constant tempo" enabled, Mixxx does not scan the entire track for beats but stops as soon as it has found a few beats and then simply assumes the next ones.
But that's only a guess, I'm not a developper within Mixxx.

And if I am right, I don't know wether to check or uncheck it by default.
For me personnaly, it would be better to uncheck it, because I play mainly pre-drum-machine-age music, but then you should also see my remark in https://bugs.launchpad.net/mixxx/+bug/1114643.
On the other hand I think that for a lot of DJ's playing only recent music, it is better checked.
And perhaps there are more of the latter playing from PC, while the "old guys" often tend to stay with there CD's.

Anyway, in my opinion, there is no right choice for this option.
At least, not for the arguments I offer here.

Please also note that for http://www.mixxx.org/forums/viewtopic.php?f=3&t=6727&p=23075#p23075, I was not totally clear.
I don't think that that topic really has to see with the discussion here.
My error, sorry.
