Menen,
<<and ask yourselves, 'WHY NOT BE STABILISED"......or can't we fly within exceedance limits.>>
What we are saying conforms to the FCTM, being at Vref + 20 at 500ft with power up is stable as per Mr Boeing. By bringing in your own ideas about stabilisation you could possibly cause dispute in the flight deck. Personally I always aim to be stabilised by 1000 ft AGL at the latest which gives me a 500 ft buffer to cover for the unexpected.
