Just a suggestion, but look at using ANOM (Analysis of Means) charts for proportions instead of the forest plots. ANOM is a nice (and better) alternative to ANOVA that permits multiple comparisons to overall system performance. I use the techniques in Nelson's book: [The Analysis of Means:  A Graphical Method for Comparing Means, Rates, and Proportions](https://books.google.com/books/about/The_Analysis_of_Means.html?id=39XUQ7vvJkEC). Since I am sometimes dealing with over 100 comparators on a graph, I also sometimes format the plot as a funnel plot. I generated a file of critical values for several different levels of alpha, since the tables in the books stop at a small number of comparators. In any case, I can send you a Tableau Public workbook that steps through all of this and contains all of the limit calculations (based on the normal approximation). I had to go back through several decades of papers to work out all of the details for the limits, but the bulk of the technique is in the book above. You can also use the R package [ANOM](https://CRAN.R-project.org/package=ANOM).

Ok cool, thank you for this! I’m certain that this is some truly spectacular advice you have give here. But I'm two pints into my Friday evening so I'm afraid all I can give in reply at the moment is my gratitude. This looks like some good options for to look into on Monday. I've not yet ventured into R much yet but I it's probably best to learn how to do this properly now while I have the time. Thanks again, i really appreciate your input.

Two pints on a Friday evening is definitely not a statistical outlier!

It is here in the UK, I'm well below the mean right now!

Yes, that was a nice surprise and quite helpful. I also got a huge boost from @postpromoter on one of my recent posts as part of their curation efforts. That has finally pushed me above 15 SP with no more SP delegated to me. I'm also glad to see your post getting lots of support too.

That's excellent, congratulations, really glad to hear that!

Yes, this one was a big surprise. I didn't try to push it with any paid promotion or anything. It just goes to show the #steemSTEM effect in action.
