Gapping and Zerp-Point

Hi Kinya

When using a light source and moving the reed toward the reed plate I always see a fine sliver of light at the reed pad side of the reed even after the light disappears on the half or three quarters of the reed length away from the pad.  It seems to me this would be inevitable if the bottom of the reed is .002" proud of the reed plate at the zeropoint.  If this is true then my question is how far this light should extend away from the reed pad?  Or am I way off track here?
