Conrad, I treated one grand with this method. It was beat up!  Most of
the glue ran between the block and plate and came out the back.  It
helped some, but not great.  

On verticals, it works great.

When I do this job, I use 1-3 oz depending on the piano.

Yeah...it will be interesting to see how this affects rebuilding.
