Climb and Descend Rates?

[ba195]

Hi,

I came to this board to just ask a little question about climb and descent vertical speeds in the 767-300ER. I hae just purchased a very high tech realistic 767-300ER simulator (package, not the real thing!). As I am yet to fly the real thing, I really need you guys to tell me this... I get vertical speeds of upto 4000 fpm using VNAV in the climb at about FL200, 300,000lbs gross weight and CLB1 set. Is this realistic? Is this like in REAL life?

Thanks
