Thanks for the reply, I guess this quote contains the information I was looking for:

"The sill panel at either end as one complete panel has strength which whatever opinions exist is a panel that forms an integral load bearing section, it is as such a testable item and it's strength at any 1 given point must not be compromised"

Our testing stations are run somewhat differently in that they only do testing and nothing else (bit like council owned ones?) so have little interest in being generous. Still have trouble accepting how my daughter's 18" holed sill passed but it will be fixed.

Thanks again
