About 50% for any reasonable opponent.

I guess it's about an extra 50%. More if you have to operate
the program by hand against a human opponent.

Objectively, not a lot. Better i think, but not really
enough difference to notice much. But against a human opponent
it has a great practical advantage. Making reasonably good
moves instantly reduces the opponents thinking time and
"upsets their rhythm".
