I'll add an observation. As others have said, It means virtually nothing in a small data size. But what i have observed over time (decades, in some cases) is that more often than not, a load (even with only 3 shots of data per string) is more likely than not to remain consistent over time (effectively, a larger data size). Looking over the multiple pages on my spreadsheet, low SD/AD loads also show a trend to be more accurate. So when starting out, i use it as an additional indicator of potential.
But, the only real data that matters is consistent accuracy over time. I can't afford to shoot statistically relevant strings when developing a load so have come to rely on these observations.
My hypothesis is that this trend would be true for high SD/AD loads, but honestly, I do not have data over time for "underperforming loads", nor have i plotted all of my data on a graph which would be skewed towards loads that perform.
Again, these are trends based on observations, not rules.
