How to Calculate TCP Throughput for WAN Links

Ask this guy:
http://bradhedlund.com/2008/12/19/how-to-calculate-tcp-throughput-for-long-distance-links/

His formula is
TCP-Window-Size-in-bits / Latency-in-seconds = Bits-per-second-throughput

This is for a single communication stream. You can max out a WAN link by generating multiple TCP streams.
