That sounds excessive to me. The only glider that gets full power all
the way is an ASH-25.

It shouldn't, since an ASH-25 is a brown weak link, not a black one.
Many clubs, pilots and winch drivers ignore this, but at their peril.
When I am driving I will refuse to launch an ASH-25 unless someone I
trust will confirm to me that it has the right link in place. 60:1 does
not bring immortality.
