Sorry, can't really help you as I've not used biscuits that often for wide
My gut feeling would be that in stock that thin you would run the risk of
the biscuits "telegraphing" on the surface of the stock.
That said, I've done plenty of glue-ups of 1/2", and much thinner stock,
with NO biscuits and never had a problem. You do need to be careful about
thin stock bowing under clamp pressure, so use cauls, duct taped bricks, or
other heavy objects (my dedicated mortiser gets called into play on large
panel glue-ups quite frequently) to keep your panel straight.
It sometimes helps, with thin material, to do the glue up in stages, but you
will still needs cauls, etc., IME.
