Don't know who else has probably tried this, but I have done it and it is effective. Using the B-24s,(has B-17 cockpits,) I use the center of the steering wheel as a sight and begin the release at that point. Somewhere between the center and bottom should be on target. Make sure your view is extended out to max. May also depend on your altitude,(I'm usually under 3000) but I have a 90 - 95% hit.
