Help! animate collapse VS motion study

Hi Guys,

the following link are 2 vid. one created from animate collapse, the other one by motion study when in inserted the collapse sequence.

vid by animate collapse - YouTube

vid my motion study - YouTube

As you can see, animate collapse works perfect but too fast. so, i decide to do motion study. but the results are off.

both have exact same settings, and did not change anything.

1.Any clues as what's going on?

2.Is there any other way I could change the speed without going through motion study?

Best regards,

Khair
