Yes, and that just confirms the original point. Mac apps often spend a lot of time in the OS apis and therefore the 68K code (the app) often ran faster on PPC than it did on 68K because apps often spend much of their time in OS apis. The earlier post said "so good that for some things the PPC Mac was the fastest 68k mac." That is true.
In my own experience, I found most 68K apps felt as fast or faster. Your app mix might have been different, but many folks found the PPC faster.
