This question was answered about two months ago. The ack has to do with a timer from when TCP/IP loads on the system. Check the archive for a better explanation.

The receiver decides the window size based on a "credit system" based on how well it received your packets in the past. Unfortunately, it's an unfair system since you have no control of how the packets do across the network, especially in the harsh world of WRED, Frame Relay switch DE's, and other outside influences. As for why you are getting on ack every two packets without it ever increasing is beyond me. It should go 2, 4, 8, 16, etc..
