Hi Paul
It sounds like f ( but that depends exactly what is written on the OT report and if you are including it. It could be e, but as the points are the same it really doesn't make any difference. If the person was having to stop every 5 seconds - to rest, they really can't go very far. I can't tell you which to put - that's up to you. You know the person - I don't.
