I don't think there's any typical. I ride in northern Colorado where 80 feet per mile is common, so my 5700 miles would easily reach around 456,000. I just started using a Garmin 530 in October, so I have the total ascent on all of my regular routes. One route has about 160 feet per mile for 30 miles, but then it's mostly downhill for the next 24. Most areas don't have a halfway point that's over 2500 feet higher elevation in only 22 miles, and a total ascent of over 3000, with all of the undulations.
