What are the on target results of this vs a $150-$300 Powder dispenser? Does anybody know of a study online somewhere?

Summary in an image from above article
This is a problem of diminishing returns. To even start measuring it $150-$600 for an accurate chronograph.
oh heck go here to see summary. Google for cost.
The difference you are looking for is towards the end. 49% of pros use high dollar scales. 47% use standard scale. If pros are evenly divided you would have to say the gains are marginal.

My cartridges are loaded in a velocity node only found through many tests. Tests are another way of saying money. With an extreme spread of 10. There is no way of correlating that with my loads being plus or minus .02 grains. But if I wasn't in a velocity node taking average velocity per grain of powder of 61.1 plus or minus .1. Velocities would vary on powder alone between 2706.7 and 2719. Already more than my ES without any other factors included. I would say it makes a very small measurable differences to me. I cannot say there is scientific proof. Way to small of a sample.
And what CM? I don't have a charge master or anything I refer to as a CM

In case you missed my edit that bolded and underlined the above. However since you bring it up I have I believe it does help and that is all that matters.

Thanks for the math lesson and choice information. The second article seemed to indicate that sad was important, but much less of a factor than wind.
I’m really just thinking that it would be cool to have a developed load in a good rifle, shot at 600 or 1000 yds in same conditions, but have 5 groups done by manual scale and trickle, 5 by dispenser +/-0.1, and 5 by $500 scale. Then compare group size and vertical dispersion....maybe even 10-20 groups of each method....unfortunately, other factors will creep in if trying to shoot and compare more than 15 groups.
