Thanks for bringing this report and analysis up again; I had wondered
recently why my own toying-around with Mike's isosurfaces didn't prompt
any max gradient warnings, but didn't take the time to investigate.

I've just published a new version that supersedes the offending
mechanism with something smarter, and should again report the max
gradient as expected, for each and every isosurface actually rendered,
yet aggregating the results for any clones.
