The last I flew was a -500 in '03 with U8.5 and it outperformed the Airbus VNAV 4:1.
I could provide a nice explanation why it is a desirable feature and not a bug if someone paid me to, still I hate it when it does what it does the best.
What you read above is folks feeling the same and trying to tweak it. Back before now, choking the throttles did the trick although it was seldom needed.
