Nikon P7000 minimum focus in macro mode

It’s a bit of a thorny issue, talking about the P7000’s focus which causes moments of wonderment, such as why didn’t it focus on the object in front of it or why does it focus only after a second press of the shutter button.  Most of the time it is great and I don’t expect perfection but I do like consistency.  One area that I couldn’t find any info about was the minimum focus distance for different equivalent focal lengths.  I suspect the value given in the spec. sheet is just for the widest lens setting.   So I did some testing and these are my results with a high contrast target and measuring to the front of the camera body.

28mm……1 3/4″ , 35mm……2 1/2″ , 50mm……6 3/4″ , 85mm……..13 1/4″ , 105mm……15″ , 135mm…….15 3/4″ , 200mm……16 3/4″

Yes it looks odd to me as well to have the focal lengths in metric and the distance in imperial but that was the tape measure I had on hand.
