If this work from aa5bpilot post 1410.....

If this post is not only led by imagination but resembles some reality, then the Asiana flight was at 2250 feet at 5 miles (recommended is 1900 feet) and descended through 1900 feet not before 4 miles.
Same with speed, which was closer to 190 knots at 5 miles than the 180 requested by ATC and it slowed through 180 kts at around 3.5 miles.

As said before, one of the main tasks in the pointy front is managing energy.
If the approach has its traps (not saying that it is a fact though) concerning speed and altitude (higher than optimal), then there is no sense in adding extra speed and hight for grandma or who ever is important to you.

This Asiana flight flew a higher and faster profile than requested by ATC or as published by the VAP, the trap was self constructed.

Edit: i,m aware that the author used FA data and there is GS influence as well, but compared to the other flown profiles this aproach looks in shambles already at 5 miles.
