A good point fogatgatwick, OEI 'Special' Procedures are designed with the inner radius for the splay at the lowest V2, and the outer splay turn radius at the highest V2+the AFM approved exceedance. With turn radii being a function of speed squared, even a little extra can take you out of the surveyed area into 'No-Man's Land'.
