With the SoundTouch algorithm there isn't much improvement with a window size below 10ms. I found a quicker way to test various parameters using mpv, which uses same/similar algo. When I get some time I'll generate random samples with various parameters and do a blind perceptual test.
mpv --af=scaletempo=stride=8:overlap=1:search=10 --speed=4 test.mp3
* Overlap in this case is a percentage rather than ms.
