| Had a call in from one of the guys from the forums on this question more regarding the comment I made about certain tank mix partners having a negative effect on the driftable fines side of things by adding an adjuvant (primarily Dicamba + Roundup).
This is the link to the study that was looking at it. A good chart on page 7 shows the VMD, %<150 (driftable fines), and the change in droplet sizes for the Dv0.1 (10% point of the droplet size distribution), Dv0.5 (VMD or 50% droplet size in the distribution)

Worth a read for sure if you have questions,
Another study by UofN similarly, but a bit denser of a read: https://www.mdpi.com/2073-4395/11/7/1321/pdf?version=1626171330
