"The one hope sick and disabled people had for PIP was the promise that the phrase "reliably, repeatedly, safely, and in a timely manner" would be included in the regulations; this would mean that each time an assessor considered an activity descriptor they would be legally obliged to view it through this prism: can the individual perform activities reliably, can they do this repeatedly, can they do it safely and can they do it within a timely manner? (e.g. within less than twice the amount of time the activity would take an average, non disabled adult).
This might seem like semantics but when applied to a disabled person’s life it is the structure that holds the frank reporting of symptoms in place. With "reliably, repeatedly, safely, timely manner" I will be encouraged to explain that I can walk a bit, but that ability to walk varies hugely. It is never reliable, requires significant medication to reduce the pain from dislocations enough to do at all, can’t be repeated in any manner that would mean I had practical mobility and is unsafe as I constantly dislocate and often fall thus relying on help from strangers to pick me up and is so slow that elderly people with walking sticks overtake me."
