How does Winscore calculate finish altitude?

A question: How does Winscore calculate finish altitude on a cylinder
finish? I assume it is based on the logger's pressure altitude
reading for the closest logger fix after crossing the finish line, but
how is that altitude adjusted for the local altimeter setting? Does
it compare the difference between the finish "altitude" and the
altitude recorded when the glider comes to a stop on the field?

What if the field has a slope, and there is a significant difference
in elevation between where the glider stops after a finish (hopefully
not because it's in a tree!) and the official altitude of the finish
point?

On a separate (but related subject), could someone please explain to
me once again how staring at an altimeter and/or doing low energy
pullups during a contest cylinder finish is safe? Or how the
sometimes smarter (from a RACING perspective) alternative of not
wasting the time climbing those extra 500 ft, instead doing an L/D max
glide to a rolling finish, stopping as soon as possible on the first
bit of airfield, is a safer alternative than just calculating a
competitive safe final glide and flying it to the finish, then flying
the pattern dictated by the conditions?

Maybe we need radar altimeters in our gliders - oops, that wouldn't
work at Newcastle, never mind....Too bad our expensive loggers don't
tell us what altitude it's going to tell the scorer we finished at in
real time, so we could salvage a botched finish...
