Cypress Knees

I've been comparing some of my current photos of cypress lagoons with shots I took ten or fifteen years ago, in the same lagoons and of the same trees. Comparing a few individual cypress knees, I've made a very rough estimate of 1-2 inches of growth over about ten years. Given that some of these knees are three or four feet above the substrate, that suggests an impressive age.

However, I've also been watching a couple of new knees (kneelets?) which have grown 1-2 inches in just the past year, so clearly it's not quite linear. Can anyone suggest any research or references on the rates of growth in cypress knees? If you can, please contact me off-list, and I'll post a compilation of responses. Thanks in advance to anyone who might be able to help, either with direct observations or good citations.
