On good stretches, the Mentor TC will spend a great deal of time between +5 and +30, and I adjust my bet ramp according to the rules: the same bet which I would make at +9 with S17 NSR will wait until +11 with H17 NSR. Playing indices are similarly precise.
You have larger numbers to work with, because the number of half-decks remaining scales to half the number of decks remaining, so the denominator is smaller during TC conversion.
One of the things which prevents me from moving to Halves, which I can also count, is the crudeness of the bet ramps and indices: you have basically -1 through +6 to work with, instead of -5 through +30 I work with using Mentor.
It makes little difference in the long run, since "all decisions are approximations," per Wong, but if you run bet ramps on CVCX for Halves (or High-Low) and Mentor, you'll see what I mean about the relative crudeness of 1DTC conversion.
