There is a relation, but it's not "simple."     The more playouts you
do, the more lines you will explore to deeper depths.

My suspicious is that with lighter playouts, you will tend to explore
more lines less deep.

The critical question is if we would get another parallel line, indicating that the search is the key to further progress, or if we would get a line with a different steepness, indicating playouts are the key. Or maybe the two are more strongly linked and both contribute. Either way I believe more data would be usefull.?
