This may sound a bit weird but if you are doing a front hand spring vault, stop thinking so much. Try not to think about where you are reaching. The main things that get you off of the table are speed and form.
If you have a good run and hurdle, try to hit the springboard with your arms low. Bring your arms to your ears while squeezing everything you have.
Assuming you body position on the board is anywhere near correct, you'll bounce over the table. Your hand will hit somewhere between the front and the back of the table. Exactly where really isn't too important for a front handspring. Your find that if your hands hit near the front of the table (and your entry angle, speed shape... are all correct), you will get more height and rotation. The further back on the table you hit you get more distance.
I know this is a bit over simplified but we already have a lot of threads on vaulting
