Measureing spine on "long tapered" shafts?

[The Ursus]

I've been using a home made spine tester for my tapered ramin shafts for the past couple of years but after a while I felt like I could use something a little quicker and more consistant for measureing spine.  So my wife bought me a Ace spine tester for Christmas to help me out.  The instructions say, if the shafts are tapered, place the middle of the taper over mid-point support/knob on the scale.  My tapers are usually 18-20" long on 3/8 ramin shafts.  

So, you guys with long tapers, do you still measure at the mid-point on the shaft?  I just want to make sure I'm doing things mostly right before I start bare shafting.

Luke,
Yes, you should place the midpoint of the shaft over the center support to get the most consistant measurement.  The quickest way is to put a mark or tape on the wall to show where the end of your shaft goes.  You'll get very consistant reading that way.  Give me a call on the toll free number on the front of your Spine-Master if you have any other questions.
