Since when is TEN DAYS 'timely' ? Seriously what excuse can there be for that other than saving a few pence ? Especially considering how they can be so deadly.
We frequently have a Thr Rev U/S for 10 days - it is the allowable period, and as you say, pennies count, so most defects do not get cured for much or all of the allowable period. Fact of life... not ideal.. but here we go.
How are they "so deadly"
They are rarely "required" in Performance Terms, and when "locked out" (correctly) somewhat less deadly than being available
