It is possible to reach almost a full point over:

1. Pe2-e4   Pb7-b5     2. Dd1-g4   Pb5-b4     3. Dg4xg7   Ff8xg7
4. Ff1-a6   Fg7xb2     5. Re1-e2   Fb2-e5     6. Fc1-b2   Fe5xh2
7. Fb2xh8   Fh2-e5     8. Th1-h6   Fe5-b2     9. Th6-b6   Fb2-c1
10. Fh8-b2   Fc8xa6    11. Pc2-c4   Pb4xc3ep

ep(22,43,0) in 11.0 => move-length average a bit over 3.76.

Without ep (nor final checkmate), my best bound is reached via the  
following sequence:

1. Pe2-e4   Ph7-h5     2. Dd1xh5   Pa7-a5     3. Dh5xa5   Th8xh2
4. Da5xc7   Th2-h8     5. Th1xh8   Ta8xa2     6. Dc7-h2   Ta2-a8
7. Ta1-a6   Dd8-a5     8. Ta6-h6   Da5-h5     9. Ff1-a6   Dh5-d1

(63,23,0) in 9.0 => move-length average a bit over 5.30.
