With a Vref at Max Landing weight of 160Kt plus say 10Kt wind correction, giving 170Kts ... say the wind is all accross, 5xGS = ROD on a 3deg slope ... so ROD would be around 850ft/min ...

So it's would not be unreasonable to see on occasions 1000ft/min correcting for rising air, going slightly into the whites etc ...

I've always felt, even on the 744, looking out at 50ft a rapid ROD can be easily seen and recovered from so long as one doesnt wait to flare at 30ft!
Also in these scenarios delaying closing the throttles helps ...

Anyway ... thats my 2cents worth ...
