When I asked about the transient range between 110% and 121%, it was not intended to say that using it would be intentional.
All of us as pilots, we will always seek to save the aircraft as much as possible. Since full-time engines are brought to harsh conditions, we may have serious problems in flight and that is not the intention.
I think it is prudent to always be under the red belt, but in case it is extremely necessary, if you need to apply 111 or 112% in a specific and rare situation, it is better to do this than to have an accident.
