Finding average velocity of a dynamic group over a longer time.

Dear Users,

I am calculating the average velocity of a dynamic group by compute reduce command. Is there is any way to find the average velocity value over a longer time like ave/time command. Since it does not allow dynamic group.

Any help would be appreciated.

​the group used for ave/time has no meaning. just use group all.
