How often does Team World redouble?

From Gnubg's "view statistics" function on a 2-ply rollout with R-K MET.
After Team World takes Team Denmark's redouble to 4, Team World:
Wins (total) 24.5% Wins Gammon on 8-cube 00.3% Wins Gammon on 4-cube 00.0% Wins Single on 8-cube 05.1% Wins Single on 4-cube 19.4% Loses Single on 4-cube 66.1% Loses Single on 8-cube 05.6% Loses Gammon on 4-cube 03.0% Loses Backgammon on 4-cube 00.2% Loses Gammon on 8-cube 00.3% Loses (total) 75.5% Recubes to 8 30.4% Redouble/take 11.3% Redouble/pass 19.1% Now, the "view statistics" feature seems to be working better than it used to (in my experience), but I can't be 100% sure the numbers reported by this feature are all accurate. The reason is that this feature also reports that Team World closed out Team Denmark twice, but that's impossible.
It may also be interesting to compare the game breakdown from the "view statistics" function to the game breakdown reported as the "Team World owns 4-cube" result:
Win Win(g) Win(bg) Lose(g) Lose(bg) View statistics 24.5% 0.3% 0.0% 3.5% 0.2% Rollout 20.4% 0.9% 0.0% 3.7% 0.1% The main difference is the rollout reports Team World win only 20.4% instead of 24.5%. I believe that is because in the "view statistics" panel Team World gets full credit for every double/pass, but would not win them all if played to conclusion, which is what the Rollout statistics reflect.
