I really do not see the advantage of going that fast. There are many small reasons not to do it, and if you put them all together there is a potential thingsget out of hand.
There is no doubth that the margin for error is smaler and that because of this you may upset your collegue.
Having said so I think you should be able to do it. One day you might need it.
So to practise it from time to time is not a bad idea but under strict conditions.
Cabin ready for ldg; approach x-list completed and a margin build in i.e. you know what to do and do it quickly when you see that the margin is melting away.
But never upset your collegue and realize that they will not always object.
