Cause I can understand better, as an example:

[...]
  hw_ptr       : 0
Playing silence
time: x0:y0:z0; elapsed time x0-00:y0-00:z0-00; Available: 32, loop iteration:
0
time: x1:y1:z1; elapsed time x1-x0:y1-y0:z1-z0; Available: 44, loop iteration:
1
time: x2:y2:z2; elapsed time x2-x1:y2-y1:z2-z1; Available: 48, loop iteration:
2
time: x3:y3:z3; elapsed time x3-x2:y3-y2:z3-z2; Available: 52, loop iteration:
3
[...]

this is what you need?
