Tried it with the H4895 and Ingenuity this evening. Averaging around 8 - 9 seconds and very few over throws. I think the previous version was slightly more reliable for overthrows but also took around 13 seconds. Still tweaking the settings a bit. I do shim the front of the V4 up a bit to reduce overthrows of the large tube. Slowing down the finish speed seamed to control overthrows. I didn’t see much difference with the buffer setting from 0.08 to 0.02. I think the scale just needs the slower speed to settle out.
