No, 040/060 is not cycle accurate at all and will likely never be 
(seeing how difficult it is to get CE mode on 68020/30 without any 
available doc of the inner working of the cpu, there's no chance we will 
ever have it on 040/060)

For now, IIRC all 040/060 instructions are considered as taking 1 cpu 
cycle, which gives the expected speed boost compared to 020/030 but is 
of course not accurate at all.
