My new Canon 20D came

My new Canon 20D came yesterday. I am so excited! I haven’t had time to do my own tests yet, but I dug up these two graphs from Digital Photography Review (DPReview) to illustrate the primary reason I decided to go ahead and upgrade:
Here is a chart of the performance of my 10D while shooting for 30 seconds in continuous mode:

See how it will do a lovely 3 frames-per-second for 3 seconds, and then slows down to only a frame per second and then slows down even more? That type of behavior is bad for race photography! I can get 34 shots in the first 30 seconds, but in the 30 seconds following that I’d be lucky to get 15-20 shots.
Now here is the chart for my 20D, again shooting for 30 seconds in continuous mode:

Five frames-per-second for 36 shots! Then 1.7 fps! Then about 1 fps after that. 76 shots in 30 seconds, that’s more than twice as many as the 10D! I can get 76 shots in the first 30 seconds, and at least 30 more in the next 30 seconds. (Not to mention that I will probably not actually shoot 5 fps because shooting that fast isn’t necessary for a race; not using the 5 fps means that the buffer will not get bogged down as quickly and I can probably average 60-80 shots per minute indefinitely.) Beautiful. And the 20D has a faster write speed, which means the buffer will clear faster. That means the camera will be quicker to “recharge” each time I have even a 2-3 second break between runners.
I can’t wait to shoot my first race with my 20D!
