Inconsistent reports from Scout regarding cpu/fpu

Hey guys, I'm emulating a CSPPC. I've installed the 060 libs and the WarpUp and PPCLibEmu libs as well. During the same emulated session scout reports different things.

Here are a few tests in a row:
CPU 68060@50MHz, FPU 68060@7MHz, MMU 68060, 604e@267MHz
CPU 68060@40MHz, FPU 68060@0MHz, MMU 68060, 604e@267MHz
CPU 68060@50MHz, FPU 68060@0MHz, MMU 68060, 604e@267MHz


After running dozens more tests, it looks like the two things that are variable are the frequencies of the 060 CPU (either 40 or 50 MHz) and the FPU (either 0 or 7 MHz). Is any of this meaningful? Will it impact any software?

Thanks!

Any benchmark trying to guess the CPU speed will fail (CPUs > 68020 runs as fast as possible in FS-UAE, which also means that the speed will vary). *Theoretically*, some software could fail if they try to detect the CPU speed and do something based on the test result. But that is quite unlikely.

Just ignore it, and don't pay attention to the reported Mhz (which doesn't even mean anything useful in emulation). What matters is how much "work" the emulated CPU can perform per unit of time
