I'll give it a go next time I'm up, but I'm pretty sure that with an practice engine failure and trimmed for the best glide distance (60 kts) the decent rate was much more than 330 ft/min.
I've just had a rummage on the Internet and I've found a site which quotes a Glide Ratio (prop windmilling, Flaps up) of 8.4:1 or 1.4 MN/1000 ft
