My guess is that we hit a sweet spot at a certain time, and we would need to constantly tune deltarpm to find it. Compiler changes, link tool changes, different options in a compile, etc can cause code to look different enough that the diff is larger at times (even if the underlying machine code is the same, just put in different places in the executable.) -- Stephen J Smoogen.
