Hi Uri,

This is strange. I mistakenly hit enter before replying, hence the blank reply.
And then I replied again but somehow the reply is not displayed.

Anyway, you are right, I meant to say that extending recaps is useful only near
the tips ie. last 3 ply. Close to the root recapture extensions expand the tree
for no good reason. That's all I was trying to say.

You have a sharp eye for detail. :-)

Best wishes,

Ross
