One method would be to calibrate with a series of  buckets that you fill by 
sampling a random source, the more samples in a bucket the more range in 
phase for that bucket. For example 1 1 1 2 2 2 3 2 2 1 0 samples sum equal 
17 so each unit equal 17/(total range of  TIC) and the bucket with 3 samples 
would be 3 * 17/(total range of TIC).
