Reefing Point measurements

Can anyone supply me with the distance or approximate distance each reef in the mainsail is from the foot of the sail or each reef point. We are having a 3rd reef installed in the mainsail and I need this information.

The measurements of the 1st and 2nd reef in the mainsail are

1st reef measured from the foot

luff        4' 8"
leech??????5' 8"

2nd reef measured from the 1st reef

luff?????????4' 8"
leech       5" 8"

Thanks,
