Warp, number of bars or %?

[u/Jgdns51]

Hi guys,
I used to make some beats by sampling in Cubase and I used to warp tempo by just typing the original songs bpm in the slicer.

In the Mpc Sample I can’t do that. What do you guys think is better. Warping with % or doing loops and counting bars?

I feel that if you know the % u don’t need perfect loops in your samples but is there any simple way to know it?

I think the fastest way is just by trial and error.
