Totally agree with Carleton.
I gauge my flying 200m capacity/progress on 25sec power. At a Track like ADT, where the nature of the wind-up makes it more taxing- it's really longer..

Quick math between my kilo file and the one linked to above- looks like mine is basically in scale with that.. Ie: my time was 10% slower and numbers were 10% lower.. Ish!
so that's a good reference IMHO
