Thanks for the files, Cage! I'll look at them as soon as I find the time.

Obviously, the new JPs only need to work with version 124. The delta calculation for JCMs is very sensitive to the JPs in place when they were loaded, so I would never expect existing JCMs to still work when the JPs are changed. Once I'm happy with the new JPs, I'll re-calculate the deltas and then see if the JCMs need to be adjusted to work better with scaling.
