My point is that you can learn from watching games more than from watching only
results because from watching only results you cannot see that one side was
lucky and from watching the scores of the programs you can see it.

I do not think that you can learn which program is better if the difference is
small by few games but you need less games relative to watching only results.

The main reason that you cannot learn by watching few games that one program is
better(even if you are a very good player and watch the main lines) is that
there are wins by luck that you cannot recognize when one program is lucky to be
in a position that it understands and it is possible that you get wrong
impression by few games.
