Yes, you do discuss a groove depth, somewhat in context with the compression of the o-ring. So, OK, we shouldn't focus on compression of the o-ring, which Oak had written about in one of his Airmail articles.
But taking your numbers from your website, and computing the compression values per the basic equation, I get the following table. Interesting, your recommendation of groove depth matches quite well Oak's recommendation of compression values of between 10 and 25%.
So while compression might not be the best way to think about this, it does appear that the two different scales really give the same range of recommendations for stack up of components.
Another question...why is there a need for a chart for the rounded edge canister and one for the square edge canister? It's all about the initial canister depth...seems to me the shape of the edge really has nothing to do with what stack up of components is needed.
