I think some also depends on the glider, some don't come down much faster in a slip compared to others. Glass ship won't add much drag slipping compared to a 2-33 in a slip.

If you're slipping a ASK21 with full airbrakes, you are going down with an L/D of 3 or worse. In most glass two-seaters, slipping will increase the drag significantly.

Not sure about that. One demo I've done with students is to fly the final at 6-700' until the runway disappears under the nose. Full brakes and nose on the numbers. Gets some speed going but gets down by 1500.'

By comparison my ASW20 with the deep flaps comes down at 4:1 with the boards out and flaps at 60 degrees. According to the book anyway. I feel like that A model 20 can come down steeper than the 21...
