Have you tried discussing this with your Regional Scientific Adviser? They should be able to offer clarification - or if they can't will either check with the other RSAs who co-authored the guidance/put you in touch with them directly to discuss specifics rather than play third party chinese whispers.
EH ran a series of one day workshops on preservation in situ, with particular reference to piling strategies last year - it may be worth seeing if they are repeating the workshops. The day was very useful (and free!).
If you are in a waterlogged site then potential degredation of the remaining waterlogged remains through changes in water table levels may be more significant than a couple of % physical destruction. There is/was some research in York on this that was presented at the IFA conference a couple of years ago that may be worth following up.
Has there been a building there before - could you reuse previous piles?
