From memory..
I'd be slightly above or at the blue line, only coming under when landing is assured. If the GA happens here (under the blue), its full power. I think the conclusion here (and one I agree with), is that each approach etc will be different. Weather, vis, wind, weight etc all need to be taken into account each time as one shoe certainly will not fit all.
Having said that, I will always follow the SOP's for the operator. But that doesnt mean I cant discuss them when we get on the ground. Many a hangar discussion has been had on these subjects, these posts are a fine example.
