Subject: safe depth to begin r3 nullmove?

Hi pulsar currently uses R2 (depth-3) nullmove untill maxdepth 7 search then it
kicks in at R3. I noticed that R3 seems to give more depth.  Pulsar also uses
futility pruning in search. if material value plus possible capture plus
futility value for that depth <alpha move is not searched.  I'm not sure this
futility pruning is so sound so what i was thinking was get rid of pruning in
search and be more aggressive with null move.  What are peoples opinions
particularly programmers? I'll probably test this somewhat but its hard to get
games against high rated opponents for pulsar so i'm hoping for some direction
before the testing.
