cycle exact cpu emulation speed, accurate ?

Toni, tell me how much cycle exact cpu emulation speed is accurate now ??
because i tested a game like aladdin with the half speed of an amiga 500 and it still smooth some little slow down but really near unseen but microcosm really slow down with half of a500 speed.
can i use this to see if a game use really all the power of the amiga cpu or is it not enough accurate yet ?
ps: i know that the amiga use more its coprocessor than the 68.000 and i didn't ask the question before because it wasn't at all accurate by the past, its a great improvement in the 2.7 winuae.

If the game relies on vertical blank interrupts (which most do) you might be able to run the CPU at 1/10th the normal speed and still have the game look and play fine. It depends on the complexity of the game. If all of the functions for a frame are completed prior to the next vertical blank, it could just sit in a busy loop waiting on the vertical blank flag to appear so it can process the next frame.
