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).
