Sorry, some of this I follow and other parts I don’t :o
the hill accels and grass work are vital to his success
ok
they must be viewed in context with volumes and speeds
ok
and must not be directly transferred to another setting
you mean geographic? 
- as if it makes no difference if his sprints are on grass in Jamaica or on a track in Scotland.
Sorry can’t follow this.
Do you mean in Scotland he would still do the same thing but use a track instead of grass?
Or
in Scotland he would still do the same thing using grass despite the grass straucture being very different to Jamaica
Or
something else again?
