The basic problem here is that 90 ft comes with high wind, the wind comes with lots of vertical and horizontal air movement, in 72 seconds you have drifted WAAY out of the field boundary, to get back sooner requires flight at considerably higher speeds than minimum sink. This is why sink rate measurements must be taken in relatively calm air. ALSO: good minimum sink performance is only useful and relevant in calm air. A very small portion of actual contest flying is done at min sink speeds, due to real world air movement. Designing primarily for min sink will not result in a competitive RCHLG.
