Neil K: I think you'll also see an improvement for 3 ply RO's if using a larger than normal SI.

yes you are right: much better CI. That prove we still need another round of testing as 1-ply is not sharp enough.

Neil K: Also I think XG's understanding and play in this position-type increase clearly if you advance the prime one space forward to be from the 5 thru 10 points which is much closer to positions that are sometimes encountered.

Right again.
