I'll be honest I just do MATs with an AT task programmed into the Oudie and use a stopwatch countdown of the min time. As I get to the end of the assigned TPs I program potential routes into IGlide and get a feel for ETA vs time remaining...of course this all happens while I am murmuring to myself how silly it is to call MATs in what is essentially a one design class (15/18 meter). ;-). Oh well.
