chore: cleanup porting notes in TuringMachine

[kim-em]

Many local notations were added during porting. To my eye, they don't improve readability at all, but if others disagree we can do something else. However, if you don't like this PR, please either resolve the porting notes alternately, or at least let me know how you would like it done (possibly just deleting them).

• The relative value is the weighted sum of the differences with weight given by the inverse of the current value of the statistic.
• The absolute value is the relative value divided by the total sum of the inverses of the current values (i.e. the weighted average of the differences).

I think removing most notation is equally readable (but this is me, reading the file for the ~first time).

Why this change? You're making n implicit again, one declaration later.
