OT, I don't know about the $125, but I know the plane tries to park on its "mark" (there are paint stripes for each type/size of aircraft expected at any particular gate - or there used to be, I haven't looked for them for some time), which gets it "close".
The motorized bridges have wheels on the bottom to allow for the final precise positioning. I see the flight attendants give the thumbs up to the ramp agent through the door window, presumably to tell them they are aligned, but I'm not 100% sure on that. If you've ever been on a plane where the ramp agent spends a long, long time trying to get the bridge aligned, you note these things (particularly when they give up on the "forward" door and move the bridge to the "middle/forward" door).
