How are you getting to the jaeger? What skill are you doing before it? Are you doing it from a giant?
A very important part of a jaeger is how you tap into it. It seems to me the most effective tap would be to drive the heels on the way down, hollow through the bottom, and then drive the heels again just before the release. The timing on the second heel drive is crucial. If you are finishing too far from the bar, you are most likely doing that second heel drive too early and/or letting go to early.
A video would help.
Disclaimer: this is a skill I have neither done nor taught before, so this is all based on how I would teach it. If other coaches with more experience than myself dissagree with what I'm saying, odds are they're right and I'm wrong.
