Honestly, two things disturb me about this notation. First of all, why is there a separate figure for the repeater? I can understand the utility of a repeater key, but how does the benefit of a repeater key carry on to a repeater figure? That doesn't make sense to me. Second, the first of three rules for using a positive or negative six is totally unnecessary; the second and third are sufficient to ensure that proper rounding (see note below) agrees with truncation. Why use the six that's

*opposite*to the sign of the number? If the rule were changed for using the six of the

*same*sign then numbers that are one-half or six times a power of twelve can be written with one fewer significant figure than with the rule for the opposite sign (e.g. 6 vs 16) But anyway, what is the benefit of

*always*using the

*opposite*sign for a least significant six, as opposed to using the sign that makes the next figure on the left even, or using whichever sign is more convenient for the given situation?

Furthermore, the symbols appear less distinct than the standard Western Hindu-Arabic numerals, at least as I see them. The symbols for three and four are almost horizontal mirror images, and that's more difficult for me to distinguish than horizontal and vertical flips as with "6" and "9" and not only that, many of the other symbols have similar shapes on the upper half. Perhaps someone can tell these symbols apart better than I...

Of course, this system has all the advantages of a balanced notation, that truncation is congruent with rounding, a minus sign is not necessary and the multiplication table is more succinct. That being said, I still get eyestrain from trying to read the figures. -meh-

NOTE: By proper rounding, I mean that a number should be rounded to whichever 'endpoint' number of a given precision is closer to the number to be rounded. That is, 56 should be rounded to zero instead of 100, 66 should be rounded to 100 instead of zero. However, a midpoint number can be rounded either way: 56 can be rounded to 50 or 60, whichever is more appropriate for the situation. An additional rule, such as round to even or round away from zero can guarantee an unique way to round a number to a given precision, but such a rule is beyond the definition of ''proper rounding'' that I use here.
