No it doesn't...

1. Wing loading is 34 kg.
2. No water
3. Polar curve is very steep at high speeds
4. It’s got a low VNE
5. It’s got flaps
6. And an engine!

It’s nothing like an LS4.

This actually looks like a good glider in it own right
but it's in a completely different category to LS4.

What? I don't know of any 13 span glider that comes
close to an LS4.

Knocking a couple of meters off the wings doesn't
reduce
your manufacturing costs much. If you're going to
build a glider it's worth the extra $$$ to make it
15M. Otherwise you end up with a PW5.

Many people say they would be delighted to have a
glider with the
performance of an LS4. This performance can now be
achieved with a
smaller span glider of 13 M or less. Can you guess
at the cost reduction
that would be possible with a 12 or 13 meter glider
compared to the 15M
LS4? Smaller factory, less materials, less labor
(especially
if hand
finishing is needed), smaller trailer, lower shipping
costs (RO-RO is by
volume, I think).
