I think Cross is very accurate on this. Problems lies in the exact beginning of the track and the exact end. (your mention 0.01 beat per 132; so a 0.01% off)

The digital track that is used by Cross has gone through many steps:
A live performance like is not accurate.
A digital registration using digital sound source for BPM is depending on the encoder and processor with potential minor shifts.

If going from hdd file to CD/DVD it gets worse. then writing speed comes in, which differs per burner (unless it is pressed).

Reading same issue, every CD/DVD uses its own speed. One main difference between 'consumer' and DJ CD gear is that the latter (price depending) has a constant rotation.

And of course when coding from one type to an other brings a new shift both in speed as well as in begin/end timing.

So a good question; but should Cross by rounding up.... or does it bring all tracks in a exact comparible state..

To make bpm more acurate limit the range of bpm search in options.

Thanx for reply..
My source songs mostly from iTunes or beatport, not ripping from CD..

Yes, I mean round up or round down like this sample
127.99 -> 128
128.01 -> 128

Should I fixed or round it using rekordbox?

if you play 2 songs where 1 is 127.99 the other is 128.01 and you beat match them they are not going to drift of even if you do a long mix
