They have been asking this for some time but the legal criteria remains the distance that you can walk so don't feel you have to answer a question about the time, just stick to quoting the distance. If you do answer with a time make sure that it is reflective of your actual walking speed, don't get bullied in to a figure that is not relevant to you.
I'm afraid we don't have enough feedback on the forum about this matter to comment on how, if indeed it has, effected reassessment results.
