To calibrate a numerical value on the logarithmic LoC scale use the binary search algorithm. Start at the midpoint say 500 and test if it's over that amount. If so pick the midpoint between 500 and 1000 and test again. If not, pick the midpoint between 1 and 500 and test if it's over 250. And so on, until you get it down to a specific value. It's more efficient than a sequential linear search for most incremental values of N.
An interesting book on muscle testing is "The Truth Reflex" by Dr. Sally St. John. You can get it at her web site

She also has a video available if you are predominantly the visual processing type.
Before running the procedure it's a good idea to correct for psychological reversal (or reversed polarity) using techniques from EFT.
More detailed techniques on correcting your energy polarity can be found in Donna Eden's book called "Energy Medicine" and she has some really excellent videos. Check it out at

I highly recommend her book to get a good understanding of the human energy system.
