Just a small point, generally, the person who says ' errr should be OK' is not the person manipulating the controls, I would expect that the handling pilot having heard those words was doing one of a number of things;
1 punching the idiot who uttered them - as there was no need to be anything less than positive as everything was under control and now we're going to get extra miles because the controller thinks we're useless
2 giving the idiot who uttered them a really hard stare - CRM friendly - because everything was under control etc
3 calling the idiot who uttered them a twxt whilst preparing to demonstrate they're incredible piloting skills because we were obviously high and now we have to get to cleared level way before the glide in the extra miles given because the controller thinks we're useless, thus regaining the moral high ground that the success of the approach was never in doubt. (when they could have just asked for a suitable number of miles)
unfortunately there is no stock 413 phrase for the question you ask so you get off the cuff replies which there may be a number of interpretation to.
